OK, you bit on my bait, so I'll reciprocate:

What exit status should be returned to the caller under what circumstances?

Once that's understood, just call kill-emacs:

,----
| kill-emacs is an interactive built-in function in `C source code'.

| (kill-emacs &optional ARG)
|
| Exit the Emacs job and kill it.
| If ARG is an integer, return ARG as the exit program code.
| If ARG is a string, stuff it as keyboard input.
|
| The value of `kill-emacs-hook', if not void,
| is a list of functions (of no args),
| all of which are called before Emacs is actually killed.
