I think Konstantin explained why it fundamentally does not make
sense to ask "which one is the Nth one after the root".  I am not
sure how running rev-list and count its output would help, unless
you are now solving a different problem (perhaps "find all the ones
that are Nth after some root", which does have an answer).
