It seems like you are using `gtar` which is more flexible than the usual `tar` command. I'd go for the following which is more general and will work on many other systems.
(gtar pipes bzip/gzip on its own anyway so this doesn't have overhead) 

#!/usr/bin/perl -w
$_=shift or die "Need file name\n";
my $command="cat $_ | ";

# Deal with common shortcuts:
s/\.tgz/.tar.gz/g;
s/\.tbz/.tar.bz/g;

STRIP: {
  $command .= "gzip -dc |", redo STRIP if s/\.gz$//;
  $command .="bzip2 -dc |", redo STRIP if s/\.bz2*$//;
  $command .="uncompress |", redo STRIP if s/\.Z$//;
  $command .="unarj |", redo STRIP if s/\.arj$//;
  $command .= "tar tvf - |" if s/\.tar$//;
  $command .= "ghostview - |" if s/\.ps//;

}
chop $command;            # remove the last pipe
system($command)
