$| works per process. So if you use one script that sources other scripts (e.g. using do $filename, require, eval $string), once is sufficient. If you start scripts from other scripts using system, exec, qx a.k.a. ``, pipe open (| somewhere in the open arguments), each script runs in its own process and thus has its own $|.
