@phil: yes, plus I mostly learned the latin ordinal series when singing the drinking song from Carmina Burana (except it has semel instead of bis), which is rather bawdy, so the dullest of documents can be suddenly enlivened a background track in my head of drunken monks ...

numbering scheme - various options best not to look on an item like this as an isolated term. various institutions use various numbering schemes, with varying levels of correspondence from language to language. For instance, EU institutions often convert letters in EN to latin ordinals in FR:

"Les dispositions des articles 19 sexies, 19 septies, 19 octies, 19 nonies et 19 decies s' appliquent aux navires de pêche communautaires autorisés par les États membres [...]<br>
Articles 19e, 19f, 19g, 19h and 19i shall apply to Community vessels authorized by the Member States [...]"
