ascending numerical order of references at one certain position in the text

When I add references to a position in the text (MS Word) where I have inserted some references already - how can I afford that the numerical order will be correct (without deleting them all and then starting to replace them with the lowest number first)?

e.g. actually it looks [10-12, 5, 13]  instead of [5, 10-13]

Thank you!!

Thank you Leanne, preferences settings are the same, actually im working with PLoS style, citation sort order is “same as bibliography”, bibliography sort order is “order of appearance”  - can I edit this when enable “other”: …?

I encountered this problem already with other styles whenever I maybe added a citation that has already been used before.

Many thanks for your advice!
