Oh, yes.  You have to call (reftex-compile-variables) afterwards to make
the change effective.  So in Lisp, this works for me.

  (add-to-list 'reftex-label-regexps
               
"\\[[^]]*\\<metalabel[[:space:]]*=[[:space:]]*{?\\(?1:[^],}]+\\)}?")
  (reftex-compile-variables)

I've just committed a fix in emacs bzr.  With that, if you change the
variable with customize, then `reftex-compile-variables' will be called
automatically.

Ah, that's unfortunate.  reftex actually doesn't know anything about
environments, so it's not even possible to skip some of them right
now...
