Subject: a beginner case question

I am using case in to determine the sorting method used for an array as
so:

  def single_choice(object)

    # sort answer order based on question.list_method
    answers = object.answers

    sorted_answers = case object.list_method
      when 'position' then answers.sort_by {|answer| answer.position}
      when 'random' then answers.sort_by {rand}
      when 'alphabetical' then answers.sort_by {|answer| answer.text}
      when 'reverse_alpha' then answers.sort_by {|answer| answer.text}
        return answers.reverse
      when 'shortest_first' then answers.sort_by {|answer|
answer.text.length}
      when 'longest_first' then answers.sort_by {|answer|
answer.text.length}
        return answers.reverse
    end

This does not because of the return statements.  However, I need to
reverse the result for those two options.  How can I do this with case
statements?  Or must I use if..elsif?
