I am not in web, but at least in my field, the "sort" question seems reasonable? You cannot always rely on the debugger being present and working -- maybe this is a remote service you cannot connect to, or maybe deployment takes hours while sending a test case only takes minutes. As for programming questions in general, they are certainly annoying during interviews, but I would be hesitant to say they are net negative. We have hired a few people who just could not program, and this was very discouraging for the team: you spend month training them, telling yourself "I am sure they are smart, I just need to help them one more time" until you realize that no, you are just wasting your time. A few cases like those, and I can see why people want to ask coding questions on interviews.
