title: Kohana orm order asc/desc?
body: <p>I heed two variables storing the maximum id from a table, and the minimum id from the same table.</p>
  
  <p>the first id is easy to be taken ,using find() and a query like </p>
  
  <pre><code>        $first = Model::factory('product')-&gt;sale($sale_id)-&gt;find();
  </code></pre>
  
  <p>but how can i retrieve the last id? is there a sorting option in the Kohana 3 ORM?
  thanks!</p>
