When sorting sequence with multiple sort columns using sequence.sort function and when sequence contains Missing.Value objects, returned from catalog query, sort fails with error: 

Error Type: TypeError
Error Value: unhashable type

 Module DocumentTemplate.sequence.SortEx, line 103, in sort

The problem i believe is in this line (in DocumentTemplate/sequence/SortEx.py, line 103):

   if not basic_type(akey):

that should be:

   if not basic_type(type(akey)):

like in case with single sort key below in that file.
