Personally, I would simplify this more by removing the dependence on the $i variable. It is fine to have $i in the code for outputting, but if you want to remove it later you can be sure not to introduce bugs: 
my $i = 0;

foreach my $hash ( @AoH_sorted ) {

  # Swap these for start with 0
  $i++;
  print "$i\t";

  foreach my $key ( keys %{$hash} ) {
    print "$key\t";
  }

  print "\n";

}
