All sorting of facets works great at the field level (count/index)...all good

The "trick" I use is to use LocalParams to give eacht facet query a well
defined name. Afterwards you can loop through the names in whatever
order you want.
so basically facet.query={!key=price_0}[* TO 100] etc.
N.B. the facet queries in your example will lead to some documents to be
counted double (i.e. when the price is exactly 100, 200, 300).
