I would try to avoid multiple consecutive writes to the TRIS register
using BSF intructions.
Try
        movlw b'11100001'
        movwf TRISA

Also, it may be possible, depending on your clock speed, that reading
the port immediately after changing a port pin to an input is giving
incorrect results, because the input register has not had enough time to
stabilize. Maybe a small delay in between would fix this.
