I once had station dock control installed, which "fixed" this and I got my docking clearance previously to those ships "requesting" it after me, but as it caused some bugs I had to remove it again.
What bugs did you encounter with Station Dock Control?
IIRC the main problem (i.e. the one big problem I recall) was that sometimes the launching of ships just ceased. In the launching queue ship after ship was scheduled, but when the time came, nothing launched. Fatal for a courier waiting for someone to open that 6.8ly wormhole.
The other reason I removed station dock control was that I felt it made it too easy to "pay" an hour or so of game time to get said free wormhole.
