Add a third process that generates your random seed, and then supplies it to the two existing processes via their command lines: 

perl -e"$s= rand; qx[$argv[0] $s]; qx[ $ARGV[1] $s];" script1.pl scrip
+t2.pl

Switch command line conventions as appropriate.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
