This one can be resolved with "First come, first serve" principle. Whoever selects the desired country first (via PM to the organizer), gets it. Basically we just continue using the standard practice seen at the Festival of Music.
I agree the end of the contest would be the best option.
Actually, I think the juries should be listed upfront, together with the schedule of matches. Only their votes for the specific matches could be kept secret until the end.
Something like this:
Rwanda
6
3
Burundi
Judge 1, Judge 2, Judge 3, Judge 4, Judge 5, Judge 6, Judge 7, Judge 8, Judge 9
Having to wait for a complete ranking from each user could be quite time-consuming, so it would probably prolong the competition quite a bit. I'd rather have the jury panels listed for each match, and then users being asked to judge their specific matches in a certain time frame.
However, if we do end up using a ranking for each user, I'd still prefer to have those rankings scratched after the group stage and everything after that resolved according to users' preferences during the knock-out stages themselves. It would allow users to change their minds during late stages, which would be something new for TISC.
