The lines in a context get reordered.  If you want to force the order
of those lines, put the exten lines in separate contexts and "include"
them... something like this:

[some-context]
include => prefix
include => my_local_e164_extension

[prefix]
exten => _XXXX,1,Prefix(3312345)

I don't know if that will solve your problem, but it is something to
consider.
