I'm not super familiar with score, but the advantage in this scenario is that voters call all input the same way and get borda + IRV + a potential condorcet winner.

If you allowed same scores then you can't do both simultaneously and/or the UX gets really funky.

you can do both simultaneously if you count ranked ballots like an election office would: you throw away all tied rankings, and rankings that come after :)
