Pushing a single tag (ref + object)?

While we are using a repo which holds all our branches (dev/test/prod), locally we have a group of developers that checkout one repo-per-branch, working on it with a cg-clone/cg-update/cg-commit/cg-push workcycle. So far it's working great.

Now, I am at a loss on how to push a _tag_ object+ref to the repo, without doing a git-push --all, which I naturally don't want to do. I managed to push the object itself, doing

    git-push repository tagrefname

But that ddn't create the ref on the repo. So I had to do

    scp .git/refs/tags/refname repostory/refs/tags/

I'm feeling a tad lost here. Surely there's a way? Or should I be crafting a patch against git-push-script? Problem is, git-push script doesn't do any parsing of the params. Grmbl.
