sortlist help?

[David Carmean]

Maybe I've been working too much this week, but I can't seem to 
figure out how to do what I want with a sortlist option, not 
even after STFW and testing for a couple of hours.   In case 
it's an obvious mistake, I'll give the attempt first:

    sortlist {
	{10.98.192/18;};
	{!10.98.192/18;};
    };

The effect that I'm after is that clients inside the 10.98.192/18 
netblock receive A records from that netblock first, and that 
clients outside that netblock receive A records *outside* of 
10.98.192/18 first.

It works for the first case, but not for the second.  In other 
words, clients outside of 10.98.192/18 are receiving just 
the standard cyclical behavior.  The relevant RRSet is:

    stealth.example.com.    3600    IN      A       10.98.16.142
    stealth.example.com.    3600    IN      A       10.98.200.4
    stealth.example.com.    3600    IN      A       10.98.200.5
    stealth.example.com.    3600    IN      A       10.98.200.6
    stealth.example.com.    3600    IN      A       10.98.16.141

What am I missing?

Thanks.
