Claiborne Sport is my favorite out of your collection, so I wouldn't retire it to the back of the shelf just yet.
In my experience, fragrances stay good a long time (years). However, as a precaution to preserve them, it's a good idea to keep them away from heat and especially light. I keep mine in a cabinet, mostly in their boxes. Some people here keep them in the fridge, or get a separate minifridge just for fragrances.
