I agree: all this complexity may not be worth it, if simple
compare-by-value in fact performs well enough. I think we should

Mark if you get things to a semi-stable state & post a patch we
can do some benching. You could actually just have two SortField
types (STRING and STRING_ORD) then we could easily swap
back & forth.
