Hi Spyk,
On the high score page it says that only the scores made in the last 60 days count for the top-scorers list. This is to make sure that new players also get a chance to rise in the lists.
Because of this only your last 3 games count which gives: 2+132+7=141.
So there is no error. Maybe you could suggest implementing an 'eternal' scores list as well, and see what other people and the admins think about that.
Hope this answers your question!
