Closing the loop here (I think you reached out to me in multiple other channels) -- Solr only supports calculating the distance between points. If you manage to index your data with a centroid point and a separate numeric field that is an approximate radius, you can get something that may be good enough for what you want to do. Basically, calculate the geodist but subtract the radius field... maybe something like this (untested!): sort=sub(geodist(),radius) desc. Use LatLonPointSpatialField to store point data if you can (is appropriate), which succeeded RPT for that.
