Yep, I you are probably correct. Yet, my scores (MBP 2.2 quad, 8GB RAM) for 32 bit are lower than 64 bit (10175 - 32 vs 11057 - 64).
After thinking about it, I would imagine the i5 2.7 to be in the 9200-9800 range, give or take). Still impressive numbers.
Here is my report, for comparison:

It's funny how I keep saying "2.5 i5" and you keep responding "2.7 i5"
Anyways, s-t posted the score below-- it's 73xx, less than the 2010 3.6 i5 dual-core.
