The equivalence is often given by ambient isotopy but can be given by homeomorphism.

Secondly, the total curvature of a type is the inf of the curvatures of tame knots of that isotopy type. Milnor shows (using proposition 1.2 in the paper), that you can always decrease the curvature slightly by an isotopy, so the inf is never attained.
