A setback for Google against Oracle

from what I saw they didn't copy comments, the new comments were very similar to the old ones, but that's because they're describing the same functionality.

Google wasn't accused of literally copying the comments, but of trying to file the serial numbers off by rewriting them. (well, early on there was accusation of direct copying of comments, but that was eliminated during the trial

As for ordering within a header. My understanding is that most of them are in alphabetical order, possibly grouped by function family (although with Java's long naming schemes, the two are pretty much the same)

If simply re-ordering the functions within the header was enough to avoid it being copying, that's just a few minutes of scripting, running software won't care

But it will be much harder to be sure that you haven't missed anything if you re-order things that way.
