Two things:

(1) Bubble sort starts from the top and works down: If the Borda order is 
    A > B > C , then Bubble compares A and B first, and then advances C as
    far up as possible, one comparison at a time. So in circular ties
    Bubble can alter the Borda order if the Borda order is opposite to the
    cyclic order.

(2) Borda's strategic problems are no worse than those of Ranked Pairs
    when it comes to three way circular ties.  In other words, Black is as
    good as Ranked Pairs in three way races.
