These are different ways to fill the same ballot! In score voting you give every party a score (in this case from 0 to 99). This was the example of a die-hard Democrat. A more moderate voter might vote something like Dems 50, GOP 60, or Dems 30, GOP 25
Actually, score voting would be better. IRV (also known as RCV) has been proven to lead to the same 2-party domination and has many disadvantages.
