Thanks for reporting!
I tried to add support for #+name'd elements in ox-texinfo.
See the attached patch.

I simply prepended an @anchor to all paragraph level Org markup
elements. However, I am not 100% sure if it is always safe to do.
May you please test the patch on your side to make sure that things are
not going to be broken? (they are not on Org manual, at least)
