-------------> http://www.ruby-doc.org/core/classes/Hash.html
hsh.sort => array
hsh.sort {| a, b | block } => array

Converts hsh to a nested array of [ key, value ] arrays and sorts it,
using Array#sort.

h = { "a" => 20, "b" => 30, "c" => 10 }
h.sort #=> [["a", 20], ["b", 30], ["c", 10]]
h.sort {|a,b| a[1]<=>b[1]} #=> [["c", 10], ["a", 20], ["b", 30]]
