why does the first example below work, and the second complains of unknown field Sort

SELECT...  
        FROM PropertyListings AS PL , Towns AS T, Counties AS C                              
      WHERE PL.TownshipID = T.ID AND PL.CountyID = C.ID
      ORDER BY T.Sort DESC                               <---  (1)  WORKS

        ORDER BY Towns.Sort DESC                               <---  (2)  FAILS


thanks
