You could have the few "best matches" listed separately in the
beginning of the list, followed by the grouping shown today.

> - Should xref always try to preserve the order in which xrefs are returned?

No!  This would make the UI even more dependent on the back-ends.

> - Suppose one xref in a.el is returned before all xrefs in b.el. And another xref in a.el is returned after. In what order will we display a.el and b.el?

See above: the best matches could be listed irrespective of the files
they were found in.
