俱舍論疏 1.148

1.148

論「已說五根次說五境」，第三一頌明五境也。頌中味先香後者，《正理論》云「越次說者，顯彼境識生無定故。」論既此釋，故知不為犯聲香在味後。

The treatise says: "Having spoken of the five faculties, next the five sense objects will be spoken of"; the third single verse clarifies the five sense objects. In the verse, taste precedes odor; the Nyāyānusāra states: "Stating them out of order is to show that the arising of the consciousnesses of those objects is not fixed." Since the treatise explains it thus, we know that placing odor after taste was not done for the sake of the metre.
