Obviously anything that puts curses into circulation would be anathema. I'm not necessarily looking for one player to have the highest score possible, so much as to have games where everyone's scores where really high.
I figure Monument is obvious, and Great Hall, Island, etc. seem like they might also contribute to a high scoring game. On the other hand if there are tons of non-terminal action cards and Vinyards that could lead to some pretty ridiculous scores as well.
