Well, asking the sage advice of the One True Perl Guru, Guru perldoc (perldoc -f open from the cmd line), we find this:
If MODE is `'|-'', the filename is interpreted as a command to which output is to be piped, and if MODE is `'-|'', the filename is interpreted as a command which pipes output to us. In the 2-arguments (and 1-argument) form one should replace dash (`'-'') with the command. See the Using open() for IPC entry in the perlipc manpage for more examples of this. (You are not allowed to `open' to a command that pipes both in and out, but see the IPC::Open2 manpage, the IPC::Open3 manpage, and the Bidirectional Communication entry in the perlipc manpage for alternatives.)
and this example
open(ARTICLE, '-|', "caesar <$article")     # decrypt article         
+              
  or die "Can't start caesar: $!";

[download]
Which could just as easily be: 
open(FH, '-|', "myscript.pl") or die "He's dead, Jim :$!";
while(<FH>) {
  do whatever with output form myscript
}
close(FH);

So, you can snarf info from one scripts output to your script using this method, or one of the IPC::OpenX methods.
Hopefully, that'll give some help.
