I would tend to put the larger applications first so they have as much time as possible to fire up.

There's a fairly plausible sounding explanation for your problem in this thread on the raspberrypi. That is the global autostart file, and works for all users If the user has an autostart file the global one is ignored and the personal autostart is used. User settings are applied last and take precedence over global settings.

Jessie creates a user's autostart file during the install, so changing settings in the global file no longer have any effect. It's recommended that you don't use sudo to edit it.
