A little wheezy, perhaps. But still kind of cool. I don't think any
other scripting language has its own special queue.

I probably wouldn't use this in production; instead I'd do the Rexx part
in a sub-procedure that pulls entries off a queue (user space, data
queue, heap, array, whatever) one at a time and does the comparison.

Why? How are those other things better than the dedicated queue?

I went through the exercise Just Because, and also because I realised
there are too few examples of RPG interacting with Rexx.

The statement would be just as true if you had left out "RPG interacting with".

I was going to quibble with how you specified the QREXQ "function"
parameter (I think it is clearer to just use a naked character literal
on the call; or, if that's not structurally possible due to the call
mechanism, then at least use a variable name indicative of WHICH
function is being issued) but I guess you've used the prevailing
convention:
