What does "awaiting reviewer selection" really mean under the "minor revision" scenario?
Try to recollect how the statuses changed when you submitted the paper the first time. 

Scenario 1: with editor/under editor evaluation >> awaiting reviewer selection >> under review 
If this is how the status had changed the first time you submitted the paper, then chances are that your paper is actually being sent for a re-review. 

Scenario 2: awaiting reviewer selection>> under review
If this was the way the status had changed, then it is possible that the online status tracking software uses the status "awaiting reviewer selection" to indicate that the paper is with the editor.
