Getting count of controlled tiles or score from controlled land?

[Common Sensei]

I was thinking of changing a trait bonus lua to be based on how many tiles the civ controls or, failing that, getting the portion of the score granted from controlled territory. I was looking to see if it was possible through lua, but so far, it seems like something that might have to wait for the DLL to be opened up.

CvGame::initScoreCalculation(void) would have it, I would guess.
