Word list sequence puzzle

I found this list of words by a Scot Morris from an old Omni magazine and I can't find the solution. What is the logic of these words (one for each letter of the alphabet) and (the order is important):

A) schwa

B) splat

C) three

D) grist

E) chore

F) flour

G) sceau

H) filch

I) rinse

J) games

K) canoe

L) reach

M) moire

N) beaux

O) queue

P) angst

Q) intro

R) aster

S) achoo

T) exist

U) awake

X) eight

Y) outdo

Z) oiled

• Hi Peter are they looking for a word at the end?

• Are the order of these words imortant or are We supposed to just work out a common theme throughout?

• Yes, the order is important, and that is the complete list. What they are looking for is to explain the sequence 1/A=schwa, 2/B=splat, 3/C=three (that's a bit of a red herring I think) etc. Commented Nov 15, 2020 at 9:26

One interesting thing is that

If you replace the consonants by 0 and the vowels by 1, you get the binary representation of the numbers 1 to 26 in order.

So perhaps that is the logic to the sequence

A suggestion for the next word in the list
