I was just thinking that literate programming and org-mode would go
great together.

I think using numbers to order the chunks is probably not the best
idea. When I wrote the one small program I wrote with literate
programming, I really liked being able to write pseudocode with the chunks
that get substituted. Like this (admittedly poor example):
def fib(n):
<<find fib_{n - 2}>>
<<find fib_{n - 1}>>
<<return the sum>>
<<find fib_{n - 2}>>=
f2 = fib(n - 2)
<<find fib_{n - 1}>>=
f1 = fib(n - 1)
<<return the sum>>=
return f2 + f1

If you put it in a git repo somewhere, I will put some time aside for
it.
