Comminges was called up to the Guadeloupe team, ahead of the 2007 Gold Cup. The 2007 edition of the tournament was the first time the country had participated in the competition. He made his debut in Guadeloupe's opening game of the tournament, playing the whole match in a 1–1 draw with Haiti. He went on to play in one of the two remaining group matches; starting in a surprise 2–1 victory over group winners Canada, before missing a 1–0 defeat to Costa Rica through suspension. Finishing the group in third place with four points, Guadeloupe qualified as one of the best two third-place finishers. Comminges subsequently started in the quarter-final match, as Guadeloupe defeated Honduras 2–1. Comminges earned his fourth cap in the semi-final, as his country narrowly lost to Mexico by a 1–0 scoreline.
