Judging from the points that were next to the medals in the Halo 4 ViDoc, and the score of the game, and can assume that the scoring system in Halo 4 will be reflected by the amount of medals you get in any given kill.
Example, a headshot medal is worth 5 points (for the sake of the argument), so we can assume that if you kill someone with a headshot, that you would get 5 points towards victory. That being said, the stock Team Slayer game in every single Halo has been 50 kills. So, 5 (points) * 50 (kills) = 250 point, so the scores are about the same, just look different.
In the screenshots below he gets awarded two medals, one must be a headshot medal. The other I think is a closecall medal because the shield was down.
Thus he was awarded 5 + 5 = 10 points for the kill.
The screenshots showed a blue killing a red, and when he did he was awarded 10 points which is reflected in the score, moments later.

This is CLEAR evidence that the scoring system has been redone and looks fresh for Halo 4.
This has also made me start to wonder how they will award Multi-Kill medals (Double Kill, Triple Kill, etc.)
I’ll walk you thru the average Multi-Kill. Adding up the Medals at the End.
You see a Red Spartan, start gunning him down with the BR, he is missing most of his shots, you kill him with a headshot, leaving your shield at about half, and your almost out of BR.
You then turn the corner, looking down a long hall, about half way down the hall there is a shotgun proped up against the wall, with an entrance into the hall just across from it. You switch to your sniper rifle, expecting some poor idiot to walk in your line of fire, and what do you know, it happens, the Red Spartan enters the hall across from the shotgun, trying to quickly grab it, without revealing his position for too long.
You miss the headshot hitting his shoulder, but fear not he hasn’t faced you yet. While he is turning towards you, you focus and shoot him in the head, your teams needs the extra score, you guys are down by 50 points, and the opposing team only needs 50 to win.
You sprint towards the shotgun, hoping that nobody enters the far end of the hall, because your shield has just started to recharge. To your disappointment your not that lucky. The far side of the hall, you see a flash of Red, and then a hail of BR bullets whizzing past your head. As you are almost at the shotgun, you glimpse at your radar, only to see that there is an enemy outside the entrance to the hall, just across the shotgun’s spawn location, your boxed in, no matter you think, I;ve been in stickier situations before.
You’ve reached the shotgun, switching your sniper rifle for the shotgun, you throw a gernade down the long hall, hoping to knock the shield out on the Spartan hurling BR fire in your direction, your shield pops just as you exit the hall.
You turn to the left just in time to see a sprinting Red Spartan closing on you very fast, about to go for the melee, a big mistake, you fire the shotgun straight in his chest from 3 feet, and down goes the Red Spartan.
You hear an explosion back into the hall, switching to your BR, adrenaline pumping, you strafe back into the hall, only to see the Red Spartan was hit with the grenade, lucky you, you quickly eliminate him with the remaining 6 shots, missing the first trio, but landing a headshot on the next trio. The body of the Red Spartan seems to do a backflip as the bullets penetrate his the awesome looking helmet armor.
Your heart is pumping and you need to get to cover, you back track to the shotgun entrance an turn to the door, only to see a Spartan with a BR, shoot you in the face.
Not bad you think, I went 4 and 1 on that spawn, and I managed to close the score to 10 points, the score being Red Team, 310 - 300, playing until 350.
Now. Lets review. The first kill was a headshot. Assuming the Scoring System that has been theorized in this thread, you would get +5 for the Headshot, and +5 for the ATM (Assist Type Medal). The second kill was another headshot, so the same two medal, +5 Headshot, +5 ATM, and another +5 for a Double Kill Medal. The next kill was a shotgun round to the chest, so no special medal, just the ATM medal, +5, and the Triple Kill Medal, +5. The final kill which was a gernade, then BR headshot kill would be another Headshot Medal, +5, a ATM Medal, +5, and an Overkill Medal, +5.
In total that would be +10 for the first kill, +15 for the second kill, +10 for the third kill, and another +15 for the fourth kill.
In total for that little spree, you’ve managed to earn 50 points tying the game. But, if you still earned close call in this game, you would tac on another +10, because the shield popped before the third kill, giving you 2 +5 close call medals, but I won’t include that.
How is this not exciting for you to think about.
