[issue33590] sched.enter priority has no impact on execution

The task schedule is executed when `s.run()` is called. There should be a
*delay = 5*  from the time the scheduling statement is executed.

If your claim is true, the priority argument is useless since it has no
impact on the execution order when `delay` values are equal. Clearly, this
is not the case since the example for `enter` at
https://docs.python.org/3/library/sched.html aims to demonstrate the use of
`priority` argument.

[issue33590] sched.enter priority has no impact on execution

[sahilmn]

New submission from sahilmn <sahilmanocha1...@gmail.com>:

`sched.enter` doesn't work as expected. If two events are scheduled with the 
same delay, then their order of execution seems to be dictated by the order of 
`enter` statements for the events instead of the priority order.

Ref attached file with example code. `sched.enterabs` works as expected.
