I'm learning about whitelist scoring in postscreen_dnsbl_sites=

/dev/rob0 mentioned using these

        postscreen_dnsbl_sites=
         ... BLACKLISTS ...
         swl.spamhaus.org*-4
         list.dnswl.org=127.[0..255].[0..255].0*-2
         list.dnswl.org=127.[0..255].[0..255].1*-3
         list.dnswl.org=127.[0..255].[0..255].[2..255]*-4

in the post at http://rob0.nodns4.us/postscreen.html.

One of the servers that's been shown to me has, instead

        postscreen_dnsbl_sites=
         ... BLACKLISTS ...
         dwl.spamhaus.org=127.0.2.[2;3]*-3
         swl.spamhaus.org=127.0.2.[12;13]*-3
         list.dnswl.org=127.[0..255].[0..255].0*-2
         list.dnswl.org=127.[0..255].[0..255].1*-3
         list.dnswl.org=127.[0..255].[0..255].2*-4
         list.dnswl.org=127.[0..255].[0..255].3*-5

Right now, two questions

(1) Does order matter in these?  I.e., is postscreen's behavior different 
whether WHITELISTS are before/after BLACKLISTS?
(2) If using Spamhaus for Blacklisting already, why not use 'dwl' too?  I guess 
what I'm really asking is about the "*UNDERSTAND* it *BEFORE* you enable" 
advice ... how/why to choose 'this' whitelist over 'that'?
