1. Modified code 
$totalscoreinv{$key1}{key2}= $totalscore;

foreach $keyscore (keys %totalscoreinv){
 print OUT "\n\nFirst key:$keyscore\n";
  foreach my $keyscore2 (sort by_score keys %{$totalscoreinv{$keyscore
+}}){
    printf(OUT "%30s %s\n", "$keyscore2= ", "$totalscoreinv{$keyscore}
+{$keyscore2}");
 }
}

sub by_score {
 $totalscoreinv{$keyscore}{$b}<=>$totalscoreinv{$keyscore}{$a};
}
