Please upgrade. 3.5.5 was released the other day, and Eliezer has new
CentOS 6/7 packages available already.

As the manual states only the TOS values in multiples of 4 are available
for use. The final two bits in the TOS field are used by the TCP ECN
feature. You should be seeing log warnings as Squid masks away those 0x1
/ 0x2 bits to produce a valid DiffServ value.
