If the game itself does not say Cross-play on it in the store then it is not possible. With some cases of cross-play coming after purchase of the digital version, I am very sure that it will then work on the vita since it is not technically a different purchase and simply an update do the existing digital copy. In your case since you own the physical copy for the PS3 you would have to purchase the digital copy in order to have access to it digitally, unless there was a code given for the digital version inside of the game case, which I am doubting.
