I agree with nobull. Whazzup? HOW do you want to compare them? Alphabetically greater than? Numerically greater than?

Alpha: 
if ( $temp_var1 gt $tempvar2 ) { print "gt\n"; }
Numerically: 
  $_ = $temp_var1;
  tr/a-zA-Z//g;
  $tnum1 = $_;
  $_ = $temp_var2;
  tr/a-zA-Z//g;
  $tnum2 = $_;
if ( $tnum1 > $tnum2 ) { print "gt\n"; }
