Lr doesn't support sort by color profile but you can create a smart collection that will filter by color profile. Clearly not the same thing, but a starting point at least. You might also want to have a look at Lr plugins by Jeffrey Friedl or John Ellis. Both have plugins that filter by various metadata, although I'm not sure that sort is included. Nevertheless, worth a look

JF data explorer is going to work perfectly - thanks!
You may also want to consider ExifMeta (a free plugin I wrote). It takes a while to get set up for first use, but then the exif metadata is forever there for instant access via Lr standard lib filters and smart collections. If you just want to round up once, then it's overkill, but if you do much of this sort of thing, it may be worth your while.
