pf/ipf/ipfw & dummynet/ALTQ are available since 5.3-R if I recall correctly.

pf.conf manual(6.1-STABLE)

     probability <number>
           A probability attribute can be attached to a rule, with a value set
           between 0 and 1, bounds not included.  In that case, the rule will
           be honoured using the given probability value only.  For example,
           the following rule will drop 20% of incoming ICMP packets:

                 block in proto icmp probability 20%

No, ALTQ cannot delay packets, you have to use dummynet for this.
