Nope, underscores are harmless.
The critical ones are tilde and white spaces, because they are subject
to globbing (cf. glob(3)). In a perfect world, they shouldn't have any
effect, but in real-world they trip over shell bugs and shell-script

Hard to know without having access to MacOSX ;)
Some OSes and tools (esp. GNU-versions) use flags or environment
variables to switch between different flavors of "POSIX-compliance" and
In most cases, they use environment variables prefixed with POSIX,
_POSIX or similar.
I had suspected you might have something active to enforce strict or
stricter POSIX-compliance. This isn't always a good idea, but provided
what you say, this doesn't seem to apply in your case.
