Not at all. Score Voting as usually defined is continuous on [0,1]. Rescaling to e.g. [1,5] doesn't change this. Restricting to integers on that does; but if there are fewer than 5 candidates, equivalent rankings can still differ for total scores. It's only equivalent if you pick an integer scale [K, K+N] with N candidates, K arbitrary.

That said, I prefer score, or even approval, as that's what strategic score devolves to, but without huge amounts of information loss.

I’m having a hard time following, can you give an example?

I’m saying that Borda allows voters to give one candidate 5 points, one other 4 points, etc. and score would allow voters to give as many candidates 5 points, as many candidates 4 points, etc.

I'm objecting to the statement that they're equivalent if you forbid ties.

This is only true when you have as many candidates as score slots.

or [0, K], K arbitrary.

because you can give multiple candidates the same amount of support in Borda if it is 0.
