What I've been done a few times is create a branch by copying the
tagged version. Example:

We make a release and tag it as /tags/rev_100.
Development on trunk continues
Change comes in that has to be deployed without integrating current
trunk changes as they aren't finished
Copying /tags/rev_100 into a branch
Make changes in the branch
Release the branch (also tagging as /tags/rev_101)
Merge changes from branch to trunk as appropriate.

Other people frequently create a branch when they need to start doing
QA on the code, and then that branch is used for testing, debugging,
fixes, etc. and when deemed release-ready, a tag is made from there.
Changes in that branch are periodically merged back to trunk as
required.

Another option you may want to explore for your tag is to not make a
"eral" directory for the tag at all, but instead set svn:externals on
your tag directory and point it at a specific revision of your trunk.
As that tag moves, change which trunk rev it points at.
