I would also score this a double. However, if the left fielder is simply playing a routine single coming her way, and then flubs it (bounces off her glove, etc.), then I would score it as a single and an error. Based on your description, the ball bounced off her glove due to the dive, so double.
We had one this year. Routine ground ball goes through the 3/4 hole. The right fielder allows the ball to go right between her legs and all the way to the fence. The runner reached third standing up. I ruled that a single with a 2 base error. It was a single all the way, but the runner should not have been able to get past first on that play.
