Please support "Traditional Mongolian Script"

@C933103: The another reason that I oppose mn-Mong is the touchability, as a matching example, the Azerbaijani can be written (commonly) in Latin and Persian (aka Perso-Arabic) scripts, however, due to the tonal incompatible, we enabled both ISO 639-1 az for Latin (the national official language of the Republic of Azerbaijan, which should points ISO 639-3 azj "Northern Azerbaijani") and ISO 639-3 azb for Persian (the regional official language of South Azerbaijan province (?) of Iran, called "Southern Azerbaijani" in SIL website).
