Most of your admissions deans, directors, and counselors have been in the business for many, many, (many) years. They have the 1600 score range branded into their brains. They know exactly what an 1180 is and exactly what a 1450 is. Tell them you have a 2060 and they will look at you quizzically. With the three tests rolled into one number, it's a lot more difficult to get a clear picture of your abilities. You could have an 800 on the writing, an 800 on the verbal, and a 460 on the math. Or you could have close to 700 on all three sections. When talking to an admissions office, it's probably easier to give them your writing section separately (i.e. I got a 1300 on math and critical reading and a 650 on the writing). However, you can always check the admissions website ahead of time and see how each school you are applying to refers to the scoring.
