Since the output of git tag is sorted by name, generally not.

Wow, I didn't know that.
But then, under the assumption that tags have names like verNNN,
that behavior ensures me that "head -1" works as intended.

Maybe I look at its implementation ( refs.c:do_for_each_ref , right?)
but this seems a tough code to comprehend, especially around
packed/loose/extra ...

Thanks,

If that assumption does not hold, you can also sort by date. See:
