For example, she'll see the socks and shoes on the floor, ask me to take care of it (usually while I'm working on something else), and then, when she returns from her errand, a half-hour later and sees them still on the floor, will say something like, "how come you didn't put the socks and shoes away?" But she doesn't really care about my answer, even if it is reasonable. She just wants to let me know that I have failed her once again.

When she does stupid stuff like this and you are busy try.
Well I am in the midst of doing something at the moment now if those socks and shoes need tending to in the real near future you might want to pick them up yourself.
My step dad use to do this. He would walk past something out of place 80 times in 10 minutes and bitch about it no matter how busy others were but would never do the simple thing. Put it were it belongs himself instead he expected everyone else to drop what they were doing and come running.
Good job standing your ground and not playing her games!
