>             Project: Mahout
>          Issue Type: Bug
>          Components: Classification
>    Affects Versions: 0.4
>         Environment: Linux
>            Reporter: Robin Swezey
>            Assignee: Robin Anil

> The array returned for a n-best call to classifyDocument is sorted ascendant instead of descendant. 
> Ex:
> {quote}
> 47-best: [ClassifierResult\{category='香川県', score=32.28281232047167\},
> ClassifierResult\{category='宮崎県', score=32.28969992600906\}, ......,
> ClassifierResult\{category='愛知県', score=32.487981016587796\},
> ClassifierResult\{category='東京都', score=32.49189358054859\},
> ClassifierResult\{category='北海道', score=32.49811200756193\}]
> {quote}
> (classification of documents for Japanese prefectures)
> Inside the classifyDocument method, just before the return statement we found this line:
> {quote}
> Collections.reverse(result);
> {quote}
> Is this a mistake or a design choice? (we are not sure, hence the "Minor" priority)
