Good point on the sorting issues with thrift - what client language are you 
using? Using perl I have not seen inconstancies in ordering.

Do your strings have any particular terminator that is being included but not 
seen in your output? Can you send out the rowkeys from scans in the HBase 
shell? That would help narrow it down.
