Since the schools aren't going to rely on what you say your score is on the application, and will wait for the official results from the LSAC, you can go ahead and apply. Since most schools do rolling admissions, it is always helpful to apply early, but you are at a bit of a disadvantage in that you don't know what your score is, and if it even within the realm of what the school normally considers, and may well be wasting your money by applying to a schools that are beyond your scores, or not applying to the schools you have a shot at. But there really is nothing to stop you from sending in the application.
