Solr 4.10 is the very first release of the export feature. It does require that all fields being sorted and exported have docValues = true in the schema. This is likely to change in the future, but DocValues will likely always provide the best indexing option for sorting and exporting full result sets.
This feature includes an entirely new sorting and exporting engine so there are some bugs lurking. I'll be opening a ticket to resolve these bugs shortly.
