I am using \bibliographystyle{ieeetr} to ensure citations are numbered by their appearance in the paper. With multiple citations however, the numbers can be out or order because of the order they appeared somewhere earlier in the paper:

\cite{paper1, paper2, paper3} ==> [5, 3, 10]

Is there a way to ensure that the numbers appear in order with multiple citations?

For anyone wondering how this works in biblatex, you need to specify sortcites=true option.

E.g. when loading the package:
