PATH_DIRS is a setopt, it *uses* $PATH.  It's not a parameter
providing alternate directories.

Anyway, it already does search like that.  You just have to chmod +x
the script files (and add a #! line if they aren't zsh scripts).

What it WON'T do is source scripts it finds that way into the current
shell.  It'll always fork a subshell for them.  Too many opportunities
for mayhem if the user hasn't explicitly asked (via the "." command)
to have his current shell altered (potentially) by the script.
