Nested attributes for ignores default scope on child model

When you setup a nested form for a parent model, the default scope for the child models are ignored.

E.g.

class Package < ActiveRecord::Base
  has_many :products
  accepts_nested_attributes_for :products
end

class Product < ActiveRecord::Base
  belongs_to :package
  default_scope :order => 'end_date ASC'
end

In the view:

<% form_for @package, :url => update_all_admin_package_products_path(@package), :html => {:method => :put} do |f| %>
  <% f.fields_for :products do |product_form| %>
     <td><%= product_form.date_select :end_date %></td>
  <% end %>
<% end %>

If you create two products:

< Product id:1, end_date: 2nd February 2010 >, < Product id:2, end_date: 1st February 2010 >

You would expect the products to be displayed in this order (sorted by end date ascending):

< Product id:2, end_date: 1st February 2010 >, < Product id:1, end_date: 2nd February 2010 >

However, they are sorted by id ascending.

In order to get the package's products to be sorted by the end date ascending, I removed the default scope (as it was redundant), and added the following conditions on the relationship between package and product:

class Package < ActiveRecord::Base
  has_many :products, :order => 'end_date ASC'
  accepts_nested_attributes_for :products
end

Maybe I'm making the wrong assumption, but should nested form attributes inherit the default scope of the child model?
