[ckan-dev] Sort metadata fields.

[Joe Tsoi]

Also if you'd like more custom sorts as you've mentioned, then it'll
be worth looking into solr sorting.

http://wiki.apache.org/solr/CommonQueryParameters#sort
http://wiki.apache.org/solr/FunctionQuery

which should alow you to define a custom function to score your
results and sort by them!
