Actually the format of titling appears to be DL# on the cover in the orange bar at the top only. On both the cover and the title page:
 Advanced Dungeons & Dragons
        Dragonlance
   Official Game Adventure
  -
      Dragons of Ice
       Douglas Niles
They are not called modules anywhere in the official titling though this term is still used to refere to them in Dragon mag and in each other, for example Dragons of Mystery page 4. I have no problem with Aerie of the Slave Lords as this is a clear title for this series that does not need to be distinguished from anything else. Clearly Dragonlance is not available, though if the modules had not spawned numerous other products it may be the title that would have been used. Dragonlance modules is not specific enough.
I am still inclined towards DL Dragonlance modules. My second choice at this time is not on your list, but very  similar to some there Dragonlance modules (DL series). -
