Actually "?" conditions make it even easier to do what you want, you
don't need to capture the return value yourself and compare it to 0
explicitly in later recipes: if you add an action line to your recipe,
this action will only be executed if the script returns 0, and you can
add another recipe with an "E" flag to deal with the "else" case.

:0
* ? your_perl_script
| pipe_to_execute_if_script_returns_0

:0 E
| pipe_to_execute_if_script_returns_something_else
