Manager Diego Maradona's men almost scored a fourth goal when Perez had to dive to his right in stoppage-time to tip Messi's shot over the bar.
Mexico, who has now gone out in the last 16 at five World Cups in a row, may feel the result could have been different without the error from the officials.
After seeing the error on the big screens, Mexican players surrounded the referee and his assistant but the officials decided not to revoke the goal.
The controversy marked the second major officiating mistake of the day at the World Cup after England midfielder Frank Lampard was denied a goal against Germany, even though his shot struck the bar and bounced some two feet over the line.
Germany, who was leading 2-1 at the time of Lampard's strike, went on to win 4-1.
The Germany-Argentina clash will take place in Cape Town, South Africa, on Saturday, July 3.
