How do I get tasks that are DueSoon and Available?

I’m working on a script to get my currently due tasks that are available, something I’ve done in a Perspective in OmniFocus. I have the condition:

task.taskStatus === Task.Status.DueSoon

but don’t see how to check for the task being Available at the same time, as Task.Status.Available is a different enumerated value in Task.Status and a task appears to have only one status value. Is there a way to check for both?

Use JS “and” (&&) logical operator to check that both conditions should be true.
