It could be a very simple error of not setting the CPU data direction register ($00) properly. When the datasette is attached the tape sense line is high (AFAIR) otherwise it's low. So setting the data direction accordingly (tapse sense line bit to output - which input by default - in the DDR) might fix the issue entirely.
EDIT: Try POKE0,31 before LOAD-ing...
