And one more potential problem.  Since the rules for the number signs
are:

  (set-char-table-range composition-function-table
                        '(#x110BD . #x110BD)
                        (list (vector
                               (concat number-sign numerals)
                               1 'font-shape-gstring)))
  (set-char-table-range composition-function-table
                        '(#x110CD . #x110CD)
                        (list (vector
                               (concat number-sign-above numerals)
                               1 'font-shape-gstring))))

which means the number signs always come _before_ the character with
which it should be composed, you should use 0 in the rule, not 1.
That number means how many characters to look back for finding the
beginning of a composable sequence, and in these two rules the
sequence _begins_ with the character which triggers composition, so
the look-back is zero, not 1.
