title: Google App Engine: how to tell sort location for a user value?
body: <p>In my <code>Main</code> model I have a <code>total_value</code> and I sort with this value. When a user enters a value I wish to tell the user the order of his <code>total_value</code>. How do I do this?</p>
  
  <p>In other words, if <code>total_value</code>s in database are 5,8,10,25 and a user enters a <code>total_value</code> of 15 how do I tell him that he will be in the 4th place? </p>
  
  <p>Thanks!</p>
