title: Sphinx and filtering by sql_attr_str2ordinal
body: <p>I don't sure it's my problem or problem in bin-release (I use Win64 binaries w/MySQL support    2.0.6-release). The problem in the fact that i have incorrect searching result when I find and sort by sql_attr_str2ordinal field. Below I attached dump with searching example.( For example i search "test" find 7 results, then I want sorted by leng_id, and key 0 is worked, but another key 1 and 2 does not work . 
  From dump I think you can understand problem). 
  Dump:</p>
