Firebending comes from the breath, in Siege of the North, Zuko's face is uncovered, meaning that he can breath and use the power of his breath of fire to free himself. Azula is completely frozen in. Plus she is mentally deranged by that time; she probably was so much in shock that she'd been tricked that it didn't occur to her in time. My theories on the matter anyway.

It's interesting to note that the only other time Katara and Azula fought one on one, in Crossroads of Destiny, Katara actually seemed to be winning until Zuko interrupted; certainly if you count the amount of hits landed.
