From what is sounds like, the game must have been called a complete game according to the rule book.
This is from the NFHS baseball rule book. I officiate baseball only and don't have access to a softball rule book but this is likely similar if not the same.
Rule 2 Section 2
Article 3
ï‚· A game ended by the umpire due to weather or darkness is a regulation game, if five full innings have been played, or if the home team has scored an equal or greater number of runs in four or four and part of its fifth turn at bat than the visiting team
ï‚· A game ended by the umpire due to weather or darkness is a regulation game, if play has bond beyond five full innings
ï‚· A game ended before the teams have had a equal number of completed turns at bat shall have the score at the end of the last completed inning
o except if the home team ties or goes ahead of the visiting team in its half of the incomplete inning
Article 4
ï‚· A state association may adopt game-ending procedures that determine how games are ended, including suspended games. However, if a state does not adopt game ending procedures, by mutual agreement of the opposing coaches and the UIC, any remaining play may be shortened or the game terminated. If a state association has adopted game-ending procedures, only those game-ending procedures may be used, should the opposing coaches wish to terminate a game.
