I could reproduce such result but I am in doubt if it is a reason to 
merge the patch. I believe, the following behavior is almost expected

list.org:
- v
- /v/
- /a/
- a

LC_COLLATE=C.UTF-8 LC_ALL= LANGUAGE= \
  emacs -Q -L ~/src/org-mode/lisp/ -L ~/src/org-mode/contrib/lisp/ \
  list.org

(org-sort-list t ?a)

- /a/
- /v/
- a
- v

LC_COLLATE=en_US.UTF-8 LC_ALL= LANGUAGE= \
  emacs -Q -L ~/src/org-mode/lisp/ -L ~/src/org-mode/contrib/lisp/ \
  list.org

(org-sort-list t ?a)

- /a/
- a
- /v/
- v

Collation rules depend on language. The question is if emphasized 
variant should be sorted first.

P.S. The thread is broken. Some new messages do not have proper 
In-Reply-To header. Original question was not referenced in the message 
with patch as well: https://orgmode.org/list/87blbac0k0.fsf@posteo.net/
