What about...
mySort xs = let myCompare x y 	
       | lx < ly = LT
       | lx == ly = EQ
       | lx > ly = GT
         where
          lx = length x
          ly = length y
      in sortBy myCompare xs
That doesn't work for me:

-- bhask.hs

mySort xs = let myCompare x y  
                | lx < ly = LT 
                | lx == ly = EQ 
                | lx > ly = GT 
                   where   
                    lx = length x
                    ly = length y
               in sortBy myCompare xs

Prelude> :load bhask.hs 
[1 of 1] Compiling Main             ( bhask.hs, interpreted )

bhask.hs:4:16: parse error (possibly incorrect indentation)

Line 4 is the first guard.
