Function task_status() - Skipped

In the documentation, I have read that:

task_status() Current status of this task. The following values are valid:

• Assigned=0
• Accepted=1
• Completed=2
• Not Started=3
• Cancelled=4
• Paused=5
• Unattended=6
• Aborted=7
• Cancelled By Exception=8
• Submitted=9
• Running=10
• Error=11

But in a Task Report, when I am defining the filters, I can select the status = Skipped. ¿What is this value? ¿12?
