Shit like this happens all the time. Remember, Rolling Stone fired the reviewer that gave Michael Jackson's record a low rating- don't want to piss off the companies that pay for the big ads, now, do we?
I'm starting to take less notice of the "numbers" since they pretty much don't mean anything anymore.
Although they're not the quickest to review games, Gamecritics.com does things "right" and by "right" I mean they don't attach a number to the game. I'm sure there's a clever pun in there too (right/write) but I'm too tired at the moment to make it. Anywho, Gamecritics just gives you the words which more often than not tells the reader what is right and wrong with a game more so than any numeric score.
