Actually I believe what happens is that your accumulative score is never cleared (like avatars and stamps) so all you have to do at the beginning of a month is play one game and you'll get you 52 points or however many you score that round added to your accululative score.
Some calculations I did when trying to get that trophy indicated that even if I played Pyramids every waking moment for months I still wouldn't get the top score or anywhere near. Its a long term thing, the only way someone can get bumped off then it seems is if they completely stop playing. Either that or people are using programs to play which would make accumulating points a whole lot faster because you don't have to "play" the game.

That's correct but the amount you would need to score everyday by my calculations would be virtually impossible unless it was done over the course of a long time.
