It's fine, better actually, to bottle cold after a crash and let it warm later to room temp in the bottles.
Everything else is the same, including the amount of priming sugar. If using a priming calculator, when asked for the temp, enter the highest temp the beer was at while in the fermenter. One thing I do a bit different when priming cold beer is to give it a very, very gentle (no splashing) stir with a sanitized spoon to ensure even distribution of the sugar in the cold liquid.
