Hashes do not define any order by definition (in Ruby), please search
the list for implementations of "ordered Maps/Dictionaries/Hashes"
this is a VFAQ.

If you can take the time to convert your hash to a sorted array of
pairs you can something like this of course.

hash.to_a.sort{ |h1, h2|
    h1.first.whatever <=> h2.first.whatever # for keys
or
   h1.last.whatelse <=> h2.last.whateles # for values
}
