Preheat oven to 350 degrees F. Decase and crumble the sausage meat and place it in a large saucepan over medium-low heat. Cook the sausage until it is almost done -- about 8 minutes. Remove the sausage from the pan, increase heat to medium, and add the onion and 2 cups of the chopped pumpkin. Sauté until the pumpkin begins to soften -- 5 to 7 minutes. Add the chopped apple and sausage and sauté for 3 minutes. Add the wine, cook for 2 minutes, remove from heat, and set aside. Combine the couscous, dried cranberries, olive oil, thyme, oregano, salt, and pepper in a large bowl. Add meat mixture to the bowl and toss to combine.
