"I got away with one, I think, today," Scott said.
After Scott's birdie putt dropped, Moore, seeking his first win on the tour, barely missed an 18-footer to tie, the ball sliding by the left edge of the cup.
Scott shot a 71 and Moore a 68 in the final round to finish regulation play at 7-under-par 273.
The runner-up finish was Moore's fourth on the tour.
"A loss is a loss, but I tied for first at the end of the day," Moore said. "That's better than I've ever done."
