How to get an ordered list of movies predictions for an item

After fitting Collab learner of the Movielens DS, i want to get for each user, his top 10 predicted movies.
learn.predict({‘userid’:xxx,‘movieid’:yyy}) gives me the prediction of yyy movie for user xxx.
I want to get a list of all of the Movieid predictions for user xxx, sorted by prediction rate.
Any assist will be appreciated.
Thanks in advance,
