We've discussed this issue at some length on the voting-project email
list. OVC is neutral on scoring methods. We will support whatever
scoring methods are in use, including IRV.

Our demo included a ranked preference contest although we did not demo
scoring for this contest. The Ballot Reconciliation System (or
"Procedure") is precinct-level tabulation and only shows how many
votes any particular candidate received for each rank order (You can't
score ranked preference at the precinct level).
