But you don't show why the AC voters would WANT to vote this way. 
Assuming the three voters prefer A to C, your example above is
equivalent to a ranked example where the same three rank A and C equal
in first place, for unknown reasons, and with the same result.

48 A    >  B=C
 3 A=C  >  B
 1 B=C  >  A
48 C    >  A=B

If the voters under either Approval or Condorcet wish to vote this way,
perhaps because they perceive B or some other unlisted candidate as more
of a threat, then I have no problem with this.  It's up to the
individual voters to weight the costs and benefits of any voting
strategy.
