unexpected output

[IICatzII]

my question here
I'm very new to Python and I created a simple number guessing game and for some reason when i enter a number that is 100 or higher it will say Higher. Why?

VarNum = "0"
while(VarNum != "27"):
VarNum = input("Guess my number from 1-99: ")
print("Your answer is:", VarNum)
if (VarNum > "27"):
print("Lower")
elif (VarNum < "27"):
print("Higher")
elif (VarNum == "27"):
print("Congratulations! You guessed my number!")
