The positioning could be done much easier in Visual Logic as well. If you wanted to position the Parenthesis text object to the left of the aggregate score.
(assuming the aggregate score is set to Center Justify, and Parenthesis is set to Left Justify).
Take the AggScore position, subtract half of its scaled bounding box width, subtract the bounding box width of the parenthesis object, and feed it into the parenthesis PositionX.
The reason for subtracting the widths is that the X Position of an object is based on where it's Pivot Point is located within the object. When set to Left Justify the pivot point will be on the left edge of the text object; and when set to Center Justify the Pivot Point is right in the middle of the object (that's why we subtract half the width).
