Rails 4 Scope Not Sorting Properly

This is my first time using scope in rails. I'm trying to sort a list of chapters by a field called :priority, an integer, in my Chapter Model. I have looked over the scope documentation but I cannot seem figure out how to get the feature to work.

Model

class Chapter < ActiveRecord::Base
 belongs_to :book
 scope :priority_sort, -> { order(priority: :asc) }
end

Controller

@chapters = Chapter.all.priority_sort

And the view

<% @book.chapters.each do |chapter| %>
  <%= link_to chapter.title, [@book, chapter] %>
<% end %>

What the view currently looks like priority/chapter_title

  -15
  About the authors

  3
  Chapter 18 Equal pay

  -13
  Chapter 2 Overview

  -4
  Chapter 11 Non-exempt employees: determining work time

  -11
  Chapter 4 Workers not covered by the FLSA

What the view looks like with a default_scope { order("priority ASC") }

  -15
  About the authors

  -14
  Chapter 1 Snapshot

  -13
  Chapter 2 Overview

  -12
  Chapter 3 Covered employers

  -11
  Chapter 4 Workers not covered by the FLSA

What am I missing here?

<% @book.chapters.each do |chapter| %>
 <%= link_to chapter.title, [@book, chapter] %>
<% end %>

Is this a mistake? If not then it's because you're scoping on something in the controller you don't use. I.e

@chapters = Chapter.priority_sort.all

If not then you can change it to

<% @book.chapters.priority_sort.each do |chapter| %>
  <%= link_to chapter.title, [@book, chapter] %>
<% end %>
