Re: so, why was face-biting so much more prevalent in tyrannosaurs than allosaurs?

False premise. Do you have any evidence that it was more common in tyrannosaurs than allosaurs??

It has been reported in Sinraptor and Allosaurus as well as in Tyrannosaurus, Gorgosaurus, Albertosaurus, and Daspletosaurus. (Heck, 100% of Sinraptor dongi skulls show it! :-) ).

So I think your premise is a non-pattern, and thus requires no explanation. You have to first falsify the null hypothesis (i.e., that the frequency is no more common statistically in tyrants than in allosaurs) before we need to start addressing a reason for it.
