Sort Plist values

I want to sort NTI Shadow.app backup job list. Since columns are not sortable in this app, it must be done in plist. What ways there is to sort by nameofjobx:

Plist looks like this:

Root
-NTI ShadowSettings
–0
—NSObjectName String nameofjob1
–1
—NSObjectName String nameofjob2
–2
—NSObjectName String nameofjob3

I might understand what you want to do if you gave an example of what the list would look like after you sorted it.

I managed to sort it by dragging items in PlistEdit Pro.
