Someone correct me if I'm wrong, but a garlic plant grows some form of a "seed" head, that will have miniature round bulbs in it if they aren't clipped off that, it's my understanding, when they are planted they'll grow like this in the first year and into a normal garlic bulb year two. I've never experimented enough to know if I'm correct, but if my info is correct I'd guess either one of those got mixed in by mistake, or if your planting in the same spot as the year prior one might've just fallen off.
Haha yeah sorry that's a bad pic. The scape is the curly thing that grows off the top of the plant in the spring, and then and flowers. If you're growing garlic, you'd normally cut the scape so that the plant puts more energy into the bulb instead of the flower. Here's a pic of the whole thing:
