print OUT $hash{key1};
print OUT $hash{key2};
etc...

If you want them in a specific order, use them in that specific order. Or do something like:

my @keys = ('one', 'two', 'three');
for (@keys) {
    print OUT $hash{$_};
}

Then, you have already predetermined your order, and can add/change it at any time.
