Confirmed.  The reason for this behaviour is that `LaTeX-env-label' does
not take care of the case that the region is active.  In fact, it seems
that most of the functions to insert environments in latex.el don't,
either.

The attached quick hack basically gives the output you suggested as
option 2, though for `LaTeX-env-label' only.

I hope that anyone else makes out a comprehensive solution that covers
other functions as well...

Bye,
Ikumi Keita
