I took a look at Nmap's scripts (https://svn.nmap.org/nmap/scripts/) and there 
are two solutions to mapping IP to ASN that the project uses:

* asn-query.nse - uses Team Cymru's database
* targets-asn.nse - translates ASN to IP using the whois of Shadowserver 

I know you already mentioned these databases, but I thought I'd let you know 
about the sources Nmap uses. I'm not aware of any more related scripts there. 
Please let me know whether this is any helpful.
