I think it's OK to let it go.  It doesn't seem like a crisis to me.
Chalk it up to experience.

One obvious idea would be to first see if the tag exists, and to fail
if it does.  You can see if it exists by doing a checkout using that
tag.  If the tag does not exist, the checkout will fail.  Note that
this is a slow process, as CVS pokes around trying to find the tag,
but presumably the script takes a while to run anyhow.

I guess this will have to be rewritten to use SVN soon anyhow.
