According to Tatsuki, Orihime was at the yellow belt level when she and the others went to save Rukia. Orihime mentions this to Uryu in ep42; so basically it was just blind luck that she was able to simultaneously knock out two Shinigami, barehanded.

That said she might have advanced two-three levels since then; training with Tatsuki, but she's no black-belt. ^^
