Usually, academic CVs aren't really the place to "sell" anything. Unlike professional CVs, academic ones are usually fairly comprehensive, but ultimately boring, listings of everything you did and achieved. Think of them as the phone book to your entire academic persona - it's a good place to check up on specific things a committee might be interested in (how many papers has this person published, and in which journals? how much money has he brought in? etc.), but not much more than that. That means that you would definitely add the information to your CV, but should probably not attempt to sell your experience through it.
The place(s) where you as a candidate would frame how you want to be perceived, and what of your activities you want to emphasize, are the cover letter, and your research and teaching statements. In that sense, you would want to emphasize your teaching experience in your teaching statement if, and only if, you think this is something central to your teaching philosophy, or if you think that this is going to be a big plus to the place you are applying to. If you really want to emphasize it you can also add one or two sentences to this end to the cover letter, but I would probably only go that far if the place you applied to is also an HBCU or has made clear that such experience is of particular interest to them (a standard blurb at the end of the job announcement does not count).
