you might try a more general approach using a regular expression replace:
field: TITLE
regexp: ^\d{0,2}[- ._ ]*
replacewith: (nothing)
this means: delete up to 2 numerical digits followed by blank(s), dot(s), dash(es) and underscore(s) from the beginning of the titel string, ie you catch things like
1.title, 1 - title, 10 title, 11_title, etc etc
beware of applying this action to titles like "99 Luftballone", "8000 miles from home" etc
