you can give it a try with the facet.sort. We had such a requirement for sorting facets by order determined by other field and had to resort to a very crude way to get through it. We pre-pended the facets values with the order in which it had to be displayed ... and used the facet.sort to sort alphabetically.
e.g. prepend Small -> 0_Small, Medium -> 1_Medium, Large -> 2_Large, XL -> 3_XL You would need to handle the display part though. Surely not the best way, but worked for us.
