As far as I am aware, Greeks can use our “Arabic” number set (1, 2, 3…), but they also use alpha', beta', … (For Greek: not just the standard alphabetic letters + a ' are used; some older letters are also used). eg., 12 = Iota + Beta + ' ; 22 = Kappa + Beta + ' . (Iota = 10; Kappa = 20.)

From what I've seen, Hebrew and Syriac, and I suspect Arabic and other Semetic languages (Coptic, Geez, etc…) use their alphabet as numbers, with slight variation. For example, if I recall correctly, various traditional Jews will not write “15” as “Yod-He”, since this number spells a name for God. So as a matter of piety or respect, it is written using different numbers which would sum to 15. (I forget which at the moment.)

Hence, in many cases, any number list would require it be different from just working through the respective alphabet.

So although this specific question concerns enumerating Greek, it potentially has much more broad applications.
