I went back in the forum to look for what was said about winning/drawing/tiebreaking. I think the most important posts were the two you'll find below.
I think the "definition" of win was ambigous.. I interpreted it as "getting 100% of the SCs on the map", but that was never stated explicitly.
However, I have a resonable hope that this will not matter.. a guy getting a draw with 40+SCs is as good as a winner from the point of view of the tie-breaking rule, so there is a strong chance that the ranking will be the same with both methods.
I'll look into it when I get a little bit more time (hopefully, this weekend)

==========Relevant "rule" post #1==========
From YCHTT, September 26
I'd like to get to 9 teams before we start as I really think the 3 team nearly anon (you know who your teammate is but nothing more) and a "winners progress" so two formal rounds of play with a third consolation round to decide who gets second and who gets third.
Each round will be three games played simultaneously so players won't be able to deduce which team is which nation set based on what nation set they already played. Solo is 7 points, draw is 6 points divided by those in the draw. So a solo *should* get you to the top but if another team solos a game and draws a third or solos the other two, it's not guaranteed. Any ties in point go to total SC count in games the team won or drew only. A concede will assume the wining team took all SCs and a solo requires the winning team to take all the SCs.
Games will be set as 100% of the SCs required to win. It will be against the rules to reveal your team in game through words. Also, no player will get the same nation twice and no team will get the same nation combo, but the nation combinations will vary from game to game so there won't be any way to deduce who will be working together on your opponents. This end up several possible ploys to male it look like one nation is another nations ally and get the third team to attack on.misinformation.

For figuring out the winners, we discussed it early in the thread. Solo is 13
. Draws are 12
 divided by teams in draw. Tie breaker is SCs owned. If each team were to solo or two teams solid with the same number of SCs in a third draw, we'll have to figure something out. But we'll cross that bridge if we get to it.
