Include Shortlisted Awards?
I will contradict Peter's answer: the CV is a living document, but it's one that needs to be supported by documentation. Something that cannot be proven should not be listed on a CV. If you only received a verbal confirmation that you were on the "short list" for an award, then you really don't have any documentation that you can provide, if called on to do so by a future employer. 

Therefore, as much as it would be helpful to list such an award, I don't think it's a good idea to do so here.
