How to handle tie?

[Osamu Aoki <osamu@debian.org>]

Hi,

I want to hear unbiased opinion on how debian-type voting should handle
case for tie like  http://vote.debian.or.jp/rank_leader2005.html .

Question:
 How should the tie be handled under DEBIAN type voting system.

Case:
Choice #1: Foo
        ties with 2 (15-15)
        is preferred to Choice #3: Further Discussion (23-6)
Choice #2: Bar
        ties with 1 (15-15)
        is preferred to Choice #3: Further Discussion (25-4)
Choice #3: Further Discussion

Note in this case, quorum was met with 30 votes :-)
