Sort by column issue

[GCRaistlin]

I have a lot of torrents with various error status, eg. Error: Invalid download state, try resuming and Error: File missing from the job, please recheck. By clicking on Status column title I expect to see sorted: first all torrents with "invalid download state", then all torrents with "missing files". But in fact I'll see erroneous torrents in confusion.

The same issue with "being checked" torrents. I'd like to sort them by checked percent (i. e., torrents with "Checked 0,0%" status should be displayed first, then "Checked 10,2%" and at last "Checked 99,5%") but again, they all are displayed in confusion.
