A while ago, thinking about this, I proposed the addition of a numerical namespace to the lucene mailing list but the suggesting didn't catch up [I also have the impression they didn't get my point, but was low priority so I dropped the subject]
I don't recall that thread, but Lucene can index numerical information as long as you take care to make sure it is lexicographically ordered. For example, I often index dates as YYYYMMDD format so that they are ordered "alphabetically".
Lucene does not provide any built-in mechanisms for turning a number into such a lexicographically ordered string, but it does for timestamps. It would only be a few lines of custom code to convert back and forth, but Lucene deals with text only, not numbers directly.
