I have this model:

class Comment
include Mongoid::Document
include Mongoid::Timestamps

field :name
field :text
field :published, :type => Boolean, :default => false

embedded_in :commentable, :inverse_of => :comments
validates_presence_of :name, :text

scope :pending, where(:published => false)
scope :published, where(:published => true)
end

So when I do this:

commentable.comments.published.count # => 3
commentable.comments.pending.count # => 3
commentable.comments.published.size # => 1
commentable.comments.pending.size # => 2

count doesn't filter, and returns the total of comments.
To filter I have to use size() instead of count().

Is this the expected behaviour?
