AFAIK there isn't a trim/cut function. If the numbers have the same ending you could define them as WARP character and they would be replaced by a line break. Would mapscript help you here? Or to make things more complicated: Couldn't you write the the shapefiles into an database? Then you could use trim/cut the value within your sql statement.
