Is the tail straight out or is it curled?
If she's immature, it is most likely a molt. What color is her telson (the end of the tail bearing the sting)? If she's an adult, it would be brown; subadults have cream-colored telsons and juveniles have white ones.
Also, I'm assuming your temperatures are Fahrenheit and not Celsius -- 85 C would give you some delicious slow-roasted scorpion.
