Sort by sql question

if I do a pagination:
@document_pages, @documents = paginate :documents, :per_page => 20,
:include => [:company], :conditions => "doc_type_id = '#{@doc_type}'",
:order => "#{order_by}"

How could I sort by doc_type.title?

Thanks,

Hey thanks for the tips on sql injection! Didn't realize that was
happening!

With the join, would I still use the :include? What would the syntax
look like?

Thanks again,
Ben
