Tigre finally broke through in the 66th minute through defender Mariano Echevarria after a nice cross from Ezequiel Maggiolo.
With the one-goal advantage the visitors were happy to sit on the lead, but Millonarios set up a grandstand finish when Jorge Perlaza scored from a long-range strike in stoppage time.
The hosts pushed on for a winner but time ran out as Tigre booked their place in the final against Sao Paulo.
