I think this might be the same bug that I reported back in May with
test -n '('
and
test -n ')'
http://www.zsh.org/mla/workers/2015/msg01225.html
Peter Stephenson fixed it less than 45 minutes later:
http://www.zsh.org/mla/workers/2015/msg01230.html
I hadn't noticed it fails on a single exclamation point as well.
It is in zsh 5.0.6 and 5.0.7. Got fixed in 5.0.8.
A lot more POSIX bugs have been fixed since, so the latest version is
recommended if you care about POSIX compliance.

As luck would have it, I'm developing a shell library too, including a
whole battery of bug and feature tests for POSIX shells. We should
exchange notes. I won't have time for the next few days, but I'll be in
touch.
Thanks,
