Well, I would say it goes in order.

Tenet 1: Never dishonor the Night Mother. To do so is to invoke the Wrath of Sithis.

Tenet 2: Never betray the Dark Brotherhood or its secrets. To do so is to invoke the Wrath of Sithis.

Tenet 3: Never disobey or refuse to carry out an order from a Dark Brotherhood superior. To do so is to invoke the Wrath of Sithis.

Tenet 4: Never steal the possessions of a Dark Brother or Dark Sister. To do so is to invoke the Wrath of Sithis.

Tenet 5: Never kill a Dark Brother or Dark Sister. To do so is to invoke the Wrath of Sithis.

That means if the Night Mother request that someone dies, then that comes first. If the Night Mother requests that you betray the Dark Brotherhood or its secrets, then you have to do that. (Dunno why she would, but if she did)

In this case, if the Night Mother requested the death of someone in the Dark Brotherhood, not doing it would be dishonoring her. Now, it's possible that Listener would disobey her, but that would be against the 5 Tenets.
