If you just want to use cake with priority tins based on the MPLS "Traffic
Class" (TC) field (i.e. the renamed original "EXP" field, see RFC5462), I
think you can use a tc flower filter (
https://man7.org/linux/man-pages/man8/tc-flower.8.html) matching on mpls_tc
values. See here for some examples:
