the overlapping applies to matching expressions, not like string 
comparison of them. So, indeed, in this case ^38.+ will match first and 
will be selected. You have to set lower priority for it.

In other words, the module goes one expression by one, order by 
priority, until it has a match. At that time it returns. It does not go 
to all expressions and try to find the longest match.

Cheers,
Daniel
