They are just adding new collections to end of list with each update, the same as they do in SS. So the order is 'order added to game' rather than anything useful. Right now there are not that many collections, so hopefully they will add a sorting option, and maybe even a search option, once the number grows. This is how it happened with SS. First the list was unsorted and random, but with not many collections, later the list grew and an update added sorting, and (much) later a search option was added (though there was well over 300 collections by then).

You can use the List of Collections and List of Collection Items here to give you the names of the collections that will reward what you want. These are sortable tables (can be sorted by any column, and the last column is 'reward type' i.e. energy, tool etc; while the second last column is 'reward name' i.e. flying time etc). In their unsorted state they are in the exact same order as the game, so using sorting to find the names of collections that are useful, and then using unsorted to find out where that collection sits in the collections tab, might help (still time consuming though).
