I understand that, due to the lower/larger ISO range of the a77 that it would receive a higher overall sensor score than the a65 (greater dynamic range, color). But as they both use the same sensor, why does the a65 score around 700 in the high ISO test, while the a77 scores around 800?

I don't see an advantage. From among the A77, A65, and NEX-7, all of which use the same sensor, the A77 and A65 have almost identical scores for SNR 18% and Dynamic Range. You may also notice that the SLTs' scores are a little bit shy of the scores for the NEX-7, no doubt due to the light lost to the PDAF system via the "Translucent Mirror".
