The benchmark seems broken for AMD. Because I've re-ran it plenty of times now and it always ends up with a different score, it's not consistent at all. I got my 7950 at 1GHz with 6355 score, then I up the core to 1,075GHz and I get 4300 even though the overclock is stable. Same with varying results at stock (850Mhz) ranging from 4,3k to 5,3k. Then I tried enabling crossfire, and scores were ranging from 6,4k to 8,4k. So yeah, there's something off.
Also ain't right that a person with 660GTX outscoring my 1Ghz 7950, no way on earth.
