The EBNF grammar has:

tanru-unit-2 = (number | lerfu-string) MOI #
number = PA [PA | lerfu-word] ... 
lerfu-string = lerfu-word [PA | lerfu-word] ... 

Your PEG grammar seems to agree:

tanru-unit-2 <- (number / lerfu-string) MOI free* 
number <- PA (PA / lerfu-word)*
lerfu-string <- lerfu-word (PA / lerfu-word)*

So I don't see how it manages to get a {bi'i} in there.

Unlikely. The intention is quite obvious. But according to the grammar,
MOI takes only a pure number.

Do you mean allowing {quantifier MOI}? If it can be done, I think 
I'd be in favour, but it would count as a change, wouldn't it?
