Incorrect sort numbers with sort_list and entries_per_page="0"

[sibyl27]

Thanks a lot for this great plugin !

I noticed that, with the following configuration, book entries have incorrect sorting numbers (they keep their "default" numbers instead of starting with 1):

[tplist headline="2" style="numbered" entries_per_page="0" pagination="0" sort_list="book, article, incollection, inproceedings"]
