I'm on the move, but try these keys in the appropriate structure commands:

numberconversion=arabicnumerals
numberconversion=abjadnumerals

Failing that, a workaround is to use the m-translate module, and define a  
translation for each the ten digits. But numberconversion=arabicnumerals  
is supposed to work.

PS \start-stopsection is now standard (\section is still there, but...)
