Only if the A voters vote ABC.  If the A voters are split evenly between
ABC and ACB then A wins (120 votes for A, 78+30 votes for B, and the 1 is
irrelevant).  Still, the general point is well-taken:  In an election
where the appropriate outcome should be obvious, the Borda result is
uncertain unless we know everybody's full strategy.
