Hi, No, the problem is easy: To sort against a field you have to index it. The field is only stored. Later versions of Lucene will complain, if the field is not indexed (as far as I remember, there was a commit about this). But currently it is sorting against nothing, so it will do the default order.
Data types are correct from your code! Please note: If you want to use the field *only* for sorting, but no numeric range queries, then use Integer.MAX_VALUE as precisionStep, else you index unneeded terms and bloat your index (see JavaDocs for explanation).
