TK2: 7500 - [NE]: 6900 (Values are completely made up, no building kills, turrets don't count).

Therefore, TK2 now have a score of 7500, and [NE] a score of 6900.

Second game between TK2 and [NE]:

TK2 wins again, but by a lesser margin, also, [NE] managed to destroy one of TK2's buildings:

TK2: 9800 - [NE]: 9400 (Killed the barracks). Now, the scores run like this:

TK2: 7500 + 9800 = +17300. No buildings killed.
[NE]: 6900 + 9400 = +16,300. 1 building killed.

The reason I'm tracking building kills is this (And I'm going to sound like Spoony): Agressive play is more important.
[NE]'s early barracks rush was probably the most exciting thing that happened all game (The rest would've been camping and "whoring" - with a great deal of back and forth by the looks of the scores)
Therefore, I suggest either a score bonus per killed building or we sort by building kills first (I prefer this option), in either case, this example leads to [NE] taking a higher place, as TK2 couldn't kill a building.

Thus the tourney/league standings:
(Rank, Name, Match Count, Total Score, Buildings Killed)
1: SoQ. Matches: 2. Points: 28,600. Buildings killed: 9. // Both by base destruction, therefore highest standing.
2: CW.cc. Matches: 2. Points: 25,900. Buildings killed: 1. // Note that Points is used to sort out who is winning when buildings killed is =.
3: [NE]. Matches: 1. Points: 16,300. Buildings killed: 1.
4: TK2. Matches: 1. Points: 17,300. Buildings killed: 0.
5: Jelly. Matches: 0. Points: 0. Builings killed: 0. // Jelly need to play! lol
6: Etc Etc.

In that example tourney table, Jelly still has two matches outstanding, and TK2 and [NE] have another one to play also.
