Hmmm... That should work.  It eventually boils down to a
smfi_chgheader call into libmilter that looks like this:

    smfi_chgheader(ctx, "Precedence", 1, "bulk");

And according to http://www.milter.org/milter_api/smfi_chgheader.html,

"Header index value (1-based). A hdridx value of 1 will modify the
 first occurrence of a header named headerf. If hdridx is greater than
 the number of times headerf appears, a new copy of headerf will be
 added."

Maybe try turning Milter logging way up and see what it says?

O Milter.LogLevel=99 in sendmail.cf, or define(`confMILTER_LOG_LEVEL', `99')
in sendmail .mc
