The functions registered with atexit() are called when the program
(main) exits. That would be when the script is done and the
interpreter shuts down (or when the interpreter dies becuase an
exception wasn't caught).
I believe the functions registered with atexit() are called in the
order they are registered. This means that *if* (I don't know) the
interpreter registers some functions before you register yours it may
not work as you want it to.

Sound like a good idea to me.
