It allows the operators to give ( / take) points to ( / from) players for various reasons.
So my guess would be that it would be used to reward the winner of a tournament, award points that you didn't get because of a bug, punish bad behavior like cheating to get a higher score, ....
maybe also to take away the points people would have gotten thanks to bugs in the scoring system as well (think of the CB testing servers at the moment).
Anyway, this is not an official message stating what they WILL be used for, I'm just speculating ^.^
