This is not a syntax issue. 1,4 copies first 4 bytes of the input record. If you don't specify position Sort automatically starts building record from the last copied byte which in this case will be first byte because its initial position.

Your include condition position is wrong. LLLL01 and LLLL02 starts at 1st byte and you mentioned your input file is FB so you would need to check for first 6 bytes. I ran the same control card with 1,6,CH include condition and it ran successfully.
Code:
INCLUDE COND=(1,6,CH,EQ,C'LLLL01',OR,
1,6,CH,EQ,C'LLLL02')
However, Unless the control card you had mentioned is partial snapshot from the entire picture, its not going to give you desired results.
You would need to use SUBSET and SPLICE in order to achieve the desired output.
