sort on facet.index?

[Derek Poh]

Is sorting on facet index supported?

I would like to sort on the below facet index

<lst name="P_SupplierRanking">
                <int name="0">14</int>
                <int name="1">8</int>
                <int name="2">12</int>
                <int name="3">349</int>
                <int name="4">81</int>
                <int name="5">8</int>
                <int name="6">12</int>
</lst>

to

<lst name="P_SupplierRanking">
                <int name="6">12</int>
                <int name="5">8</int>
                <int name="4">81</int>
                <int name="3">349</int>
                ...
...
                ...
</lst>
