You can set an environment variable in the one parent script that you're looking for. E.g. $ENV{RUNNING_FROM_FOO}=1; in foo.pl, then in bar.pl test if ($ENV{RUNNING_FROM_FOO}) { ... }.

Update: I see the Joost already suggested an environment variable, but you seem to have missed it (as did I). So it's probably worth saying again anyway :-)
