If you take each digit in the hint and rearrange them in numerical order, you get

0111122223334556666667889

The middle number is 4, with twelve numbers on either side. This points to the 4th Doctor.

Also, 0 and 9 appear with the same frequency as 4. The beginning and end together suggests some kind of circular game piece, which aligns with hockey pucks or inner tubes- discs, too, but we just had that. Or maybe the endgame will be autonomous, since autonomous was previously at the beginning- beginning and end together.
