This is exactly what we did although we solved this problem in the
context of trying to prevent advertent/inadvertent changes
to /tags/tagname. The script allows adds to /tags but not to subdirs
of /tags, as well as prevent modifications of under /tags. This same
mechanism would prevent the second tag creation as it would infer that
you are trying to illegally modify an existing tag.
