Runs while pegging

Play went as follows:
Husband: 3
Wife: 1
Husband: 2=3 points
Wife: 4= 4 points
Husband: 1 =?
I say nothing, count is 11, he thinks he get 3 point because he has 3 in his hand. Who's right?

Nothing

There is no score by playing the final Ace...because husband is missing a 3 on the board. It doesn't matter what he has left in his hand, it matters what is out of his hand and on the table.
