Update
I remembered something "quirky" about JavaScript's default sorting algorithm: it coerces values to strings and sorts them lexicographically.
The reason the plain sort worked was because all then numbers had the same number of digits. If they had varying numbers, it would have sorted them like this: [2, 20, 3, 30].
I have made updated JSBen.ch benchmarks using arr.sort((a, b) => a - b) (I can't manage to login to JSBench.me):
