Illegal property values + sorting

Me and my inattention... Reading the official documentation always helps, and I'm very sorry for being not careful reading it. Thank you very much! Also I noticed that for some reason I used Has type::Text instead of Has type::Date for one my properties whilst the rest were and are well-typed. Fixed it locally.

P.S. It looks like YYYY-MM can work as well thus I need neither xx nor 00. That's awesome!
