Sort won't work

This is for a interior design firm, so the similar criterias are, type (retail, office, law office, medical office, food court...50+ categories), sq footage, contract amount, region of country, office that did project, scope of work, construction (new, remodel, historical), client type

Things like sq footage and contract amount don't have to be exact but within a range of say 10%+ or -. Region is concentric, city, state, group of states, half of country, country(and I don't immediately see how this could be done with AI::Fuzzy

Many of the types are related so an accountants office scores more similar to a law office than does a doctors office. So there are very few black and white comparisons, I am trying to figure out how to do all these shades of gray without several huge comparison tables, but maybe that is what it will take.
