Winning is winning, no matter how you do it? http://en.wikipedia.org/wiki/Kobayashi_Maru#James_T._Kirk.27...
Or, because you've achieved the mission goals?
You're begging the question. Achieving the same goals with different rules is a different game. Using stilts and a machine gun to get a ball in a hoop is not basketball.
I don't think the Kobayashi Maru test rules said anything about "don't try to break the game". Success can result from relaxing an irrelevant requirement.
