I just checked Metacritic, and the highest scoring Final Fantasy so far is only 92. That said, and combined with how different FF13 is to the traditional JRPG or FF series, I could see it receiving a lower score due to that.
EDIT: Correction, FF9 scored a 94. I didn't even check that one since I assumed X or VII would probably have had the highest scores
