Both the tags schedule and scheduled exist, but usage is fully identical. It seems inefficient, could they be merged into schedule (which is used slightly more often)?
According to the list of top users for schedule, you are capable of suggesting a synonym for it, and there are more than five other users with a score of 5. The top user is Mitch♦, and I guess his vote as a mod would be binding. So, perhaps you should suggest scheduled as a snyonym, and pester Mitch to vote on it. Considering how long we have been waiting on Tag Synonym Request: [scanning] -> [scanner], that might be fastest way.

1@Seth Nooooooo! What happened to pestering Mitch? (Thanks! Could you also take care of that scanner tag?)– muruJan 2, 2016 at 16:56
1@muru Already done :)– SethJan 2, 2016 at 16:59
@Seth Perfect, thanks :) Jan 2, 2016 at 18:54
I would tend to agree. A brief look at the questions involved indicate that the existing schedule tag could easily be used for the questions using the scheduled tag. I don't believe there is a downside to taking this action.
