I also agree that small capitals have a tertiary or quaternary differences, but it's not clear if they are a variant of lowercase when used as a font style for all letters, or of uppercase letters. So I bet they should have the same distinction as between lowercase and uppercase, so that case-insensitive collation (which ignores secondary differences) will work correctly even if tertiary and quaternary difference are kept to sort accents and other minor variants, probably by sorting small capitals between uppercase and lowercase letters at the same collation weight. The simplest way to allow tailoring is to map small capitals as secondary differences between uppercase and lowercase letters, and let a tailoring remap them in one simple operation to quaternary level, where a 1-weight gap has been left in quaternary collation weights to allow such remapping without needing shifts of weights.
