Sadly one can't use wildcards in functions. This clunky function might serve:
#FUNCTION strip_ords {%right(%1, %if(%pos("1st ", %1), %eval(%pos("1st ", %1)+3), %if(%pos("2nd ", %1), %eval(%pos("2nd ", %1)+3), %if(%pos("3rd ", %1), %eval(%pos("3rd ", %1)+3), %if(%pos("th ", %1), %eval(%pos("th ", %1)+2), 1)))))}
As an exercise, I've left it to you to double check if I have enough parentheses.
If the only space in the item separates its ordinal position from its name, you could use:
#FUNCTION strip_ords {%right(%1, %pos(" ", %1))}
