Hi,
well, what exactly do you mean by "sorting"? The order of the entries must be preserved, e.g.

['A','C','B'] ne ['A','B','C']
[download]

So it means that the result of the above should be

A     A
C    
B     B
      C
[download]

or

A     A
B    
C     C
      B
[download]

If I understood you correctly, sorting would result in

A     A
B     B
C     C
[download]

Or not? This I don't want ;P
