1. In the previous code, everything is fine. You can order you records by adding order method and send it field (id). 
class User < ActiveRecord::Base
  scope :find_by_age, ->(age) { where("users.age = #{age}").order(:id) }
end
 
2.I assume that the developer incorrectly calculates the number of posts. If a user has a large number of posts, we need to add a callbacks to posts model. In this callbacks we will be increment or decrement users field posts_count. And when we will be call search we can increase our perfomance.

3. Write test for 
class Message
  def mark_as_read
