Putting aside all the factors at play such as the other singles released the same week and amount of airplay, it's kind of the right number really. It's not as good as any of the four Quarry singles which all ranked higher, and it's higher than 3 of the 4 Ringleader singles (though I preferred In the Future to this track).
I just thought it'd go top ten because of the recent tour dates and buzz, good and bad, surrounding Morrissey at the moment. Not too far off, though, if it does stay at 13.
Plus it's a song recorded for a greatest hits album, not a new album, and it has no new b-sides and he's losing on the download side of the business. So...not bad in this day and age I guess!
