Comment 2 for bug 1212082

I would like to argue :)
1. I don't think the order of tags is meaningful for end user. Since it's "tag", the attributes of an object.
2. The clause "order by" will causing "file sort". It would be nice if we can avoid that.
Anyway, I will make some tests to check how to balance the performance and serviceability.

Thanks for your attention, markwash.
