It might be better to use two calls. First call requestAnimationFrame and in the first callback, set the column and make a second rAF or rIC call. In the second callback, do your sorting. Also, it should be possible to do the sorting in a way that mostly doesn't block the browser. The data itself (if it lives outside of the DOM) can be sorted in a web worker. The DOM obviously blocks the UI thread, but you could do small batches of changes with a rAF or a rIC in-between each. Or, you know, just stick with setTimeout(..., 0) since that's already working for you.
