I just note that if you use a (non-proportional) single-winner method that 
orders the candidates (maybe with ties) in the order of preference, then your 
results are not proportional. I.e. if 51% of the voters like A and B, and 49% 
like C and D, then you elect A and B. A proportional method would elect one of 
{A, B} and one of {C, D}. Maybe that is however what you want (two best 
candidates with no proportionality requirements). CIVS seems to support also a 
proportional mode (but maybe that is not what you want).

Kristofer Munsterhjelm already noted that you could use that one vote (or 
multiple votes) directly to determine the preference order. That would be a 
good and simple approach.

I also note that if you want all the votes to be secret, you could allow also 
Mark Shuttleworth to cast a secret vote. He could give also an additional 
separate public vote that would be used to make the decision in case there is a 
tie. That vote could be required to rank all the candidates, so there is no 
need for further tie breaking. His public vote could just rank the candidates 
in a random order if he doesn't want to use his personal preference order. If 
he would give a random order, then we would already be quite close to just 
using a random order (lottery) to solve ties.
