Unfortunately I don't think there's much we can do about it. The problem is that the hooks which create the desktop files for click applications and scopes behave differently: the one for applications appends the version number, the one for scopes doesn't.
The ideal solution would be to modify the scopes hook so that it generates the desktop files with the version number. Until that is done, I'm afraid the only solution is to explicitly specify the <desktop-entry> element in the .application file -- I've also filed bug 1541717 because this possibility is actually missing in the new hook configuration for online accounts, and obviously it needs to be added.
