You're almost there, just change the print statement to: 
print "$value -> $key\n";

If all of the values are numeric you should change the comparison operator to <=> like so: 
foreach my $key (sort { $HoH{0}{$a} <=> $HoH{0}{$b} } keys %{$HoH{0}} 
+) {
    my $value = $HoH{0}{$key};
    print "$value -> $key\n";
}
