You have this almost correct.  Sourcing for interactive mode has
nothing to do with it.  It always applies to the scriptname argument
passed to a new zsh, so it has to be in effect before zsh searches for
the script.

For completeness, the following also enable path_script:

c) "zsh --emulate sh scriptname" or "zsh --emulate ksh scriptname"
d) zsh is invoked by the name "sh" or "ksh" via a filesystem link
e) ARGV0=sh or ARGV0=ksh is in the environment when zsh is invoked
