edit: still confused, by point, do you mean round point (eg: 1-0 Kind of thing, or 30-29 point)
If you mean we remove 1 point from a teams score in a round for 3 teamkills, that can be scripted, but that'd mean M have 2 points still and SWK have 3, InC have 4 and JOKER have 1, as the actual round scores aren't changing because of the teamkill rule, just 1 point is taken off per 3 teamkills,
Eg: the scores A28-B28, and team A just made their third teamkill, the score would then be A27-B28, right?
