Probably I misunderstood, but: do you *know* which version worked
well? I.e. when you start gitk, can you point to the working
commit and are just wondering how to revert to that one?

Then gitk's "reset ... branch to here" could help you. Right-click
the desired commit and reset the branch.

There's no need to have a tag for this. You can even create a
tag afterwards for any commit you like. It's just an alias for
the commit id (sha1).

If you cannot identify the working commit, then please forget
my answer and follow the "git bisect" proposals.
