I have a theory on this---
I think Peter had and used Voldemort's wand (Yew, very powerful, etc) and 
whatever Peter had tried to do, he didn't perhaps get the best results (from 
another wizard's wand) and was certainly not accustomed or fit to handle 
such a powerful wand.  

I think this is a possibility because I see Peter as bening made to go with 
Voldemort, at least to the house at Godric's Hollow to show him the location 
and break the charm (yes, I know he could have written it down, but I think 
Volde would make him come along).  Peter then could have witnessed 
everything and after it was all done, have retreived the wand (maybe he even 
has other wands-- Lily's and James'???)
Also, it is evident that Voldemort has his wand back in GoF, after Peter 
returned to him and was with him.  I am pretty certain that Fallen Voldemort 
could not possess and wield a wand so someone had to have saved it from 
the wrecjkage at GH and then given it back to him by the beginning of GoF 
(when the wand is used to kill Frank Bryce).  There are only two options:  
Crouch and Wormtail (or anyone of several ESE:  Snape, etc).  As Crouch is 
dead and gone, I see Wormtail as the most likely candidate.
