Yes, I hope I made my point clear below.

I think I might not have made my point clear: the sort function above
sorts one of the sub-lists.

It is not good enough for each sub-list for the same reason: the order
produced by string-lessp is not the same as the actual order.
I will try to explain the situation using the regular English alphabets
and the extra letter þ (which was used in place of "th" AFAIU).
The core English alphabets are a-z then we have some extra alphabets
like the þ above. When we have a list containing _both_ a-z and þ, the
order produced by string-lessp is wrong. To work around this issue, we
decided to break the list into two. I think we were on the same page
till here.
When I did as you suggested and broke the list into two -- a-z and þ --
and sorted the sub-list that only contained a-z with string-lessp, the
sorted sub-list was not in the right alphabetical order i.e., instead of
"a b c d ..." it was "a c b d ..."
I hope the above makes the situation clear.
