So why have you set the lock screen to a longer delay than your power save
mode? By default, the lock screen is activated immediately after power save
mode kicking in:

That's correct for the lock screen, but the shield (eg. without the password
page after the shield) is supposed to come up as soon as the screen goes into
power saving mode.

That doesn't really make sense to me. You're basically asking for removal of
the the "Lock screen after blank for" option. If you don't like it, why do
you change it in the first place? Just leave it at the default value, which
is doing exactly what you're asking.
Again, screen shield != screen lock.
