Hi, Jim. Yes, that numbering is correct for that album.
There should also be "A Something Extra" bonus 45 rpm disc, in a plain white sleeve (it is mentioned on the back of the main sleeve, below the other titles.
Also there should be a 24 page lyric booklet, both of which are mentioned on the front cover.
Re the odd numbering sequence, I also have a box sets of swing records, each with with three discs, and they're numbered side1 &6, 2&5,3&4, so it's not an uncommon practice.
Enjoy Stevie, he produced some great music; try his early stuff.
