That's what I was referring to, when I said "not very well". Being 
required to reveal the full plain-text
ballot would make the system vulnerable to pattern attacks, but if the 
system has been augmented
to deal with that, I'm very interested to learn about it.

The counting rules for STV are relatively complicated. There are many 
decision points involved,
and multiple counting operations, all of which need to be verifiable 
independent of the voting authorities.
Do you have a paper, or other description of your system, that I can 
look at?
