May I ask what is your source for using these diacritics ? George Ifrah (in
vol. 1, fig 17.48, uses only macrons (1 for 1..900, 2 for 100..900 000).
George Ifrah gives as references A. Mallon, Grammaire copte, Beyrouth, 1956
and W.C. Till, Koptische Grammatik, Leipzig, 1955. I do not see when U+0331
would be used.

Same here http://mycopticchurch.com/coptic/lesson2.asp.
I suppose a good article on this topic could be « Les chiffres coptes » by
Messiha Hechmat in Le Monde Copte 24: 25-28, 1994.

Add additional macrons ?
