Is there any further work being done on this issue ?

I'm looking for something similar, not necessarily aggregating a score, but I 
would like to able to use sort and group.sort together such that the group.sort 
is applied with in the group first and the first document of each group is then 
used as the representative document to perform the overall sorting of groups.

According to that documentation "sort=popularity desc will cause the groups to 
be sorted according to the highest popularity doc in each group".

What I want to do is something like "sort=popularity asc, group.field=label, 
group.sort=popularity desc, group.limit=1" so essentially the most popular 
document in each group, but in least popular order across the groups. This 
works when running a single non-distributed instance of Solr, but when starting 
Solr with numShards >= 1 it behaves differently.

I wrote up a description of the problem on the mailing list, but no one 
provided any feedback:
