I actually asked the question again in the new AP thread. When DARS updated for the new AP tests what we thought was a misprint last year was there again.
A friend of mine who went to A&M in the 90s 
said she had calculus credit for 142 and still had to take 141. She thought it was a dumb rule that surely had been fixed. Doesn’t sound like it though.
Math 141 is a pre-req for Math 142. AP calc gets you out of 142 but not 141.
Did you take any notes on AP Econ by any chance?
