The monks have pointed out that hash order is not preserved. I just want to point out that one method I often use to preserve the order of the input hash is to use an intermediate array:

#!/usr/bin/perl
use strict;
use Data::Dumper;
my %HoTypes = my @HoTypes = (
    'PythonQuestions' => [ '[PythonQuestions|Python Questions]', 318, 
+3, 10 ],
    'OffTopics'       => [ '[OffTopics|Off Topic Post]',         500, 
+3, 10 ],
    'notes'           => [ 'Notes',                              283, 
+3, 20 ]
);

# retrieve the keys in the original order
@HoTypes = @HoTypes[map { $_ % 2 ? () : $_ } 0..$#HoTypes];

# and use the keys recorded in the array
for my $T ( @HoTypes ) {
        my $nodeStr = $HoTypes{$T}[0];
        print "$T -> $nodeStr\n";
}
