From what I've been able to tell from looking at creative commons license blurb they tend to be for artistic mediums, and in fact when I contacted them about open sourcing some of my own work I was recommended to use MIT,BSD, (L)GPL, although they do offer a combination license so that you can open source the code and graphics in one fell swoop.
The combination licenses would be 'CC-GNU GPL', 'CC-GNU LGPL' or 'BSD'.
