No >100% scaling. At 2.5 GHz standard speed, by the way he talks about

reference motherboard containing RD790 chipset packed two HD 2900XT cards

...and a little later, the score:

When running at 2.5GHz, the 3DMark06 score ended at 23.768, so we were thrilled to see such a good score coming from two 512MB cards.

Again, no mention of overclocking the 2900XTs.

But 3 GHz system had overclocked 2900XTs:

When clocked at 3.0 GHz and equipped with two overclocked HD2900XT cards in CrossFire...

"Better than 100% scaling sorta jumps out, don't you think?"

Maybe. It all depends on how the benchmark is calculated. It may not, and indications are "is not" scale linearly with the various score increases. That could lead to super-linear scaling if the CPU portion of the benchmark scales more than usual lineararity with the clock rate increase and is weighted higher than the others.

Again, as noted, Theo isn't exactly the most trustworthy of authors. So it could be all made up. But that isn't obvious on the face of it.
