Sorting Results of a Multi-valued Faceted Search

Question

Using bobo-browse MultiValueFacetHandler to gather multi-valued faceted results, how do I sort these facets by the top-scoring document in each facet?
For example, if:

Document d1 has facets f1 and f2 and score 3.5
Document d2 has facets f2 and f3 and score 4.7
Document d3 has facets f1 and f3 and score 0.9
Document d4 has facets f2 and f3 and score 2.2
Document d5 has facet f1 and score 3.4
Document d6 has facet f3 and score 5.4

I would expect these results in this order:

f3, f2, f1

Thank you.

There is no straightforward answer to this question. Documents don't have enough information to associate different fields, so only easy solution is to generate derived fields whose value is a concatenation of other field values and use this to build facets.
