The following two URLs show sort working but the sequence of the "sort comma delimited elements" is different from the document that I found and gave in the previous message.  This leads me to believe that there was a later version 1.0 document.  I would naturally prefer the sequence that we have implemented which is below but don't mind too much:
tag path, schema, case, missing value, direction,pica,1&maximumRecords=10&recordPacking=xml,pica,1&maximumRecords=10&recordPacking=xml
