What about the games included with the mod? Those aren' t v32 games, are they? I cannot see the yellow "!".

How can you tell if so cheated? We have an ongoing tournement and one user has a so much higher result than the rest. He is almost 10x better than the others.

And it is weird that the person holds the current highscore on that game and the all-time highscore is much higher and also from that person. I think that the all-time highscore has been achieved recently whereas the current highscore is older. Did that person cheat?

even the games with a ! in the list seem to be vulnerable to users altering their scores. I don't really see an easy way of fixing this, though.

Well, I have been watching the user logs, but with some of the games the game score does not match with possible scores for the time duration the user played. For instance a user scoring 1000000 points in 20sec's is impossible in most games. Or if you know there are only a certain amount of enemies or objects to destroy in a given level, and the user manages to score much higher without ever going past that level... those are just some of the indications cheating is going on.
