For me it would depend on what type of job I was going for (and how many citations I had!!). For an academic post, then yes I would definitely consider including citations as this may just give you the edge over another candidate with a similar CV and may help yours to really stand out, particularly if you have impressive numbers to put in! If you just put the publications and then something like (citations: 11) after it then it is subtle enough to not come across as pompous, in my opinion.
On the other hand, for non-academic jobs it is probably irrelevant in a lot of cases as they won't really care about the details of your publications. That being said, if you were going for a research role in industry, for example, then it could be considered relevant and I would probably put them in. Your CV is there to sell you and your achievements, so no point in hiding your light under a bushel :)
