I think that your idea is right, but I can't conclude it.
Please show us your code.

Using String#to_i method [
http://ruby-doc.org/core/classes/String.html#M000787 ],
you can convert a String object to a Integer object.

For instance:

# you want to sort this hash
hash = { "1" => "test", "2" => "aaa", "10" => "bbb" }
# sort : not expectation
p hash.sort { |a, b| a[0] <=> b[0] }
# sort : expectation
p hash.sort { |a, b| a[0].to_i <=> b[0].to_i }
