You can either create an actor class whose actor has the image you want (whether saved in a file or programmatically created) or you can create a new world whose background is the image you wish to show. Either way, the score will have to be drawn (or created ). This constructed image will usually then be drawn onto another image that is set as the actor image or the world background with the 'drawImage' method of the GreenfootImage class. The color of the text can be specified in the constructor previously mentioned; or you can set the drawing color of the image to 'drawString' on with the 'setColor' method (both of the GreenfootImage class).
