Re: how-to sorting after group_by ?

In ruby 1.9.2,

...group_by(&:cli).sort

Otherwise, you can''t because hashes are unordered by nature.  You can 
sort the keys and then access the hash using the sorted keys.  Or, you 
can use ActiveSupport::OrderedHash, and try to figure out how to 
initialize it when you have a Hash.
