I do not see how short ranking can cause a
circular tie. Short ranking means that a voter is saying:
"If my preferred candidate(s) is (are) not also preferred,
to the other candidates, by the voters, then I accept
whatever other candidate the other voters will choose. If
every voter short-ranks and votes for only one candidate,
then this electorate will have converted the preferential
ballot election into a FPTP election. The FPTP winner is
also the Condorcet winner since he has beaten every other
candidate, in a pairwise contest.
