sorting

[#1]

Is there a way in a pivot table to sort my delivery ID's in order?

Like This below

3AM

8AM

1PM

3PM

May be using Match function

Match(DelivID, '3AM', '8AM', '1PM', '3PM', .....)

[#3]

This is what I got

by adding this 

match(DelivID,'3AM','8AM','1PM','3PM','5PM-WK','8PM','11PM','OUTS','STAT',' ')

I think you did it as a calculated dimension, why don't you try this now

Dual(DelivID, Match(DelivID,'3AM','8AM','1PM','3PM','5PM-WK','8PM','11PM','OUTS','STAT',' '))

Script : you can add

Dual(DelivID, Match(DelivID,'3AM','8AM','1PM','3PM','5PM-WK','8PM','11PM','OUTS','STAT',' ')) as DelivID

In this was you don't need to add calculated dimension in all the charts in which you use this field.
