"key.bat" runs the program "key.ex". That program uses the built-in
function get_key() to get the keycodes, while you use wait_key() for
this purpose. But this should not cause the problem, since as far as I
know get_key() and wait_key() return the same keycodes.

Let me guess: Your program is a Windows application (say "myprog.exw"),
right? "key.ex" is a DOS program. If you rename your program to say
"myprog.ex", then it is a DOS program and will probably work as expected
(a least regarding the point in discussion here).

I just realized, that wait_key() (as well as get_key()) in some cases
returns different key codes, depending whether the program runs on DOS
or Windows (what about Linux?).

So this might be the explanation, but not the solution. I think a
Windeows application must use a differnt way to get the desired
information. I'm sure someone else here knows how to do so.
