I think it's a tie.
Found this quote in TSSAA Girl's Soccer regulation PDF
F. Each district may choose to break ties in its regular season contests using a modified tie-breaker system. Each
district shall decide whether or not to use this option by taking a vote from each school prior to the start of the
season. If a district votes to use the option for its district contests, the following tie-breaker procedure shall be
used in regular season:
Teams will play two 10 minute Golden Goal (Sudden Victory) overtime periods. At the end of the first 10
minute overtime period, teams shall change ends. There shall be a two-minute interval between periods. If,
at the conclusion of the two 10 minute Golden Goal (Sudden Victory) overtime periods, a tie still exists, the
tie shall be broken with the penalty kick procedure outlined in the NFHS Rulebook.
