What happens when the trial judge makes a misstatement in sentencing?

In U.S. v. Abdel-Aziz, the Fourth Circuit in a per curiam opinion for the panel of Judges Luttig, Michael, and Traxler affirmed the sentencing order issued by the trial, notwithstanding the judge's misstatement at the sentencing hearing of saying "Count 3" when he apparently meant to say "Count 1."
