Does your programming language allow you to implememnt a SQLite external function which takes a value and returns a string indicating which range its in ? This would allow you to implement triggers on INSERT and UPDATE which automatically set a 'category' field in the table. Then you could filter on value, or use GROUP BY, or other things.
