If i remember it correctly, the syntax is:

 bgp_community.delete([(65000,*)]);
 
Because (123,*) is syntax used in 'community sets', delimited like
other sets by [ .. ], and community delete now accepts community sets.
Therefore you can also do something like:

 bgp_community.delete( [(65000,*), (65123,1), (65123,10)..(65123,25)] );
