To answer Waynes original question, I use all three languages. If I want
to write a simple TSO script or use the SDSF API I reach out for REXX.
If I want to make use of a massive standard library I use Python.
If I'm writing integration code I use Lua.
Lua is a niche language designed to be embedded (which is why I like
it). It doesn't have a huge standard library and makes no assumptions
about file systems other than fopen().
This is good because when I ported it I could easily run Lua scripts
from PDS libraries. I can run it in CICS, anywhere LE C runs. Because it
was designed as a configuration language
I use standard Lua scripts for config DSLs. Lua supplies the parser.

Well, at the moment Ruby looks better than Python, and I'm wondering about Lua

Perl cool, been using it for about 30 years, but Python is a different
beast.
More coherent and sound language model.
Better and sounder module support.
Math, math, math but not about math.
Supported by a huge, lively, and leading-edge user/developer community.
You're going to love Python on z/OS. It's revolutionizing IBM i.
