One of the reasons secondaries are usually wound on the outside is they are usually heavier wire and so offer more protection to rough handling.

I your case the secondary is thinner wire so being wound first makes
good protection sense.

Steve is correct, it does not matter here.

YES ! It makes a difference in some particular circumstances ( signal transformers), but not usually in the case of a basic unit like this.
