I am reading the LICENSE-Codea.txt distributed inside the Codea Runtime Script and i am searching for a license for the spritepacks, can an app be sold in the store using spritepacks contained in Codea?

The TL;DR version is: They are under the Creative Commons 3.0 License and you need to credit them publicly in your app. They suggest:
