It's "iffy" that the screw is in the shoulder unrepairable area. It looks too close for me to call, but a tire shop would know in a heartbeat. Or at least they can confirm by dismounting the tire and having a look inside.
I would not use an "unrepairable" tire even as a spare, but that's just my opinon. I'm not sure you would need two either - depends on the tire wear. Depending on what website you look at, 4/32" is about the limit. With only 10km I wouldn't expect that much wear unless you are unusually rough on your tires!
