I'm not sure why you are using the outer loop below?
A different interpretation of "the first occurence to in the second array is not zero"; mine prints 1 1. No idea which interpretation (if either) is actually what is wanted.

I like that your new version reports undefs instead of (@AoA, 0) if there is no match.
