OK so how exactly surplus gets transferred? I thought it is random like 
described in
http://stv.sourceforge.net/votingmethods/random so it is not clear which 
  vote is considered as surplus and thus which #2 position vote counts. 
As I understood it maybe my vote for #1 was not considered as surplus of 
winning person so my #2 position does not count at all. Correct or not?

I didn't mean you should vote for other than your #1. I just think that 
with ranking method the next positions have bigger effect so it really 
doesn't matter much if you put someone on first or second place (or rank 
them as 100 or 90 on 0-100 scale) when council has 5 members. With STV 
it is very significant since your one vote is counted really only for 
one person (and most likely the first one on the list if the candidate 
is popular).
