According to the XBMC wiki, the XBMC scraper looks for formats along these lines
name.s01e02.ext
name.s1e2.ext
name.s01.e02.ext
name.s01_e02.ext
name.1x02.ext
name.102.ext
Unfortunately drone does not really offer much flexibility in exactly how the files are renamed, with just a couple of toggles only. Would it be possible to offer more flexibility here? I’ve just switched over from SB and really like the interface, but this kind of irks me.
Not sure what the XBMC scraper has to do with it, since Drone already supports a number of naming formats that XBMC is able to process without issue.
More customizable naming is already on the feature request list on Trello though: https://trello.com/c/LWBr1lGE/177-fully-customized-naming-like-sabnzbd
Well, the reason is because I’ve used one of the formats from the XBMC wiki and have become pretty accustomed to it, would be nice if i didn’t have to convert all of them. 
Glad to see it’s on Trello, i did look there but must have missed it. Would be nice to have even more than SABnzbd, ie: Video Source, video/audio encoding, etc. Just a thought!
