My first thought is, after you've answered all of your questions (#pages, simplex/duplex, pagesize, copies, title), why do you keep looking through the file? Why not do something like

my $more = 5;
while ( $more && <FILE> ) {
. . .
# $more-- with each successful assignment so $more will be 0 when all 
+five variables are known
. . .
}

If I remember correctly, everything you need from your postscipt file is in the first few lines right?
