Orientation of a PCR product in a T-vector

I was screening colonies carrying a PCR product cloned into a T vector
by PCR, I was surprised to see that 90 % (and 100 % in another cloning)
of the colonies had the PCR product ligated in the same orientation.
I thought there was an equiprobablity of insertion in the 2 direction
for T-cloning ?
What is the rule for this (if any) ?
Thank in advance,
PS I ask this because I will need soon some "inverted" PCR product (the
rare orientation in the above examples) for subcloning purpose ...
