the sum function or the map one are not parsed correctly,
doing this sort, works as a charm...
sort=score+desc,sum(Num,map(Num,0,2000,42000))+asc
but
sort=score+desc,sum(map(Num,0,2000,42000),Num)+asc
gives the following exception
SEVERE: org.apache.solr.common.SolrException: Must declare sort field or
function
