@PinguinDirk Sure that also works, I would contest it's shorter though. You can do Sort[GatherBy[Transpose[{labels, list}], First], #1[[1, 1]] < #2[[1, 1]] &][[All, All, 2]] then it is shorter, but only by 7 keystrokes :)

Another idea for the sorting might be: Sort[GatherBy[Transpose[{labels, list}], First], First@#1[[1]] < First@#2[[1]] &][[All, All, 2]] (possibly slower than your ideas, but at least it's rather short :) )
