You need to look at texturing the cubes with the car numbers. Only 10 number images are needed (0-9), you can then create the textures with any number. These types of question are not physics related, you would be better off asking them in the Blitz3D Programming forum tbh.
Regarding the dead car count, it's easier to detect the 'Roll' angle of the car body to see if it's upside-down or not. Use a counter to make sure it has been upside-down for a few seconds then increase the dead car count. If you want to use collisions instead, look at the CarDemo-DetailedC demo to see how collision information is obtained.
