Here's another way to explain the same numbers.

Initial opinions:
6	B>A>C (or B>C>A)
2	A>B>C (or A>C>B)
5	C>B>A
4	A>C>B

B would win. But before the election the two A>B>C voters will change  
their (sincere) opinion to (sincere) B>A>C. As a result C will win. B  
thus got more first place support but lost the election.
