Gabriel, I don't know about the specific implementation of join_keys_to_values, but ruby's hash behavior changed between the 1.8 series and 1.9 and later[1]. In ruby 1.8 hashes are enumerated in a seemingly unsorted manner, while in ruby 1.9 and later hashes are enumerated in insertion order. If you are on ruby 1.8, it would be worth seeing if you experience the same issues in ruby 1.9 or later.
