"A good reason to alphabetize is that your text editor can alphabetize a group of lines." That seems like putting the cart quite precisely in front of the horse. What text editors can easily do is not nearly as important as what's useful. I don't think it's clear that strict adherence to an ordering of several properties per selector is useful - at least as much as bracket-handling and such - and if one has enough properties per selector that it takes noticeable time to find a particular property once you've located a selector, that's very likely a problem with one's CSS. Now admittedly, I use less, which makes CSS pretty concise, but if there are tens of properties for any selector, something needs refactoring.
