Thanks for your attention to this, Nicholas.

The situation is improved, though not entirely fixed. However, the
problem may well be on my end. I tried a few settings and wasn't able
to get quite the expected behaviour; I may simply not understand the
required syntax for org-list-demote-modify-bullet.

I should also mention that I am a coward and thus don't live on the
bleeding edge. After cloning the git repo and setting up a temporary
.emacs pointing for org mode to the master branch,
M-x org-version reports:
Org-mode version 7.8.09 (release_7.8.09.236.gdbc6f)
This seems to me to confirm I have the HEAD of master as of an hour or
so ago, but it is best if more competent eyes verify this.

My minimal .emacs:
; /home/brian/code/foreign/org-mode is where my git clone lives
(setq load-path (cons "/home/brian/code/foreign/org-mode/lisp" load-path))
(setq load-path (cons "/home/brian/code/foreign/org-mode/contrib/lisp"
load-path))

(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))

(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)

(setq org-directory "/home/brian/docs/org")

(setq org-default-notes-file "~/docs/org/inbox.org")

(setq org-alphabetical-lists t)

; In the comments below, "n" and "A" stand for
; arbitrary number and alpha characters in bullets
(setq org-list-demote-modify-bullet
;       '(("+" . "-") ("-" . "+") ("1." . "A.") ("A." "1.") )
;   Works demoting n. --> A.; fails A. --> n. with
;   Wrong type argument: stringp, ("1.")

       '(("+" . "-") ("-" . "+") ("1." . "A.") ("A" "1") )
;   Works for n. --> A. However, A. --> A.

;       '(("+" . "-") ("-" . "+") ("1" . "A") ("A" "1") )
;   n. --> n. rather than to A.
)

I used a simple org file containing only:

- foo
  + bar
    - baz


1. spam
   A. ham
   B. eggs


for my tests. With the version of org-list-demote-modify-bullet active
above, demoting "B. eggs" yields "A. eggs" one level indented whereas
what is desired is "1. eggs". As noted in the comments, the earlier
commented version yields a Wrong type argument error and the item "B.
eggs" remains in place, unchanged.

Thanks for the (at least) partial progress. Is the rest my error? If
so, what setting ought I to use?

Best,
