It counts first preferences of candidates defeating the potential
winner pairwise. A CW will always have a score of zero under this
method.

However, you are right about there being a little cause for concern:

34 A>E>F
33 B>E>F
33 C>E>F

I believe this is an E-F tie. E's win over F is worthless due to E's
lack of first preferences.
