Would this be a situation for a Front Script?

Instead of a front script, handlers in the card script would probably  
be easier. This takes advantage of the Rev message hierarchy. If the  
mouseEnter and mouseLeave messages aren't handled in the objects  
themselves, the messages pass on to the card.

Small suggestion, although perhaps not so important in this case.  
When you have many items named basically the same but appended with a  
number, I find it more useful to make the names into two words. For  
example, "box 1", "box 2", "box 115", etc. Then it's easy to get the  
numbered part by using "word 2 of the short name of whatever".

The handlers in this case might look like this:

## in card script

   on mouseEnter
     if word 1 of the short name of the target is "box" then
        set the backcolor of the target to <color>
     end if
   end mouseEnter

   on mouseLeave
     if word 1 of the short name of the target is "box" then
        set the backcolor of the target to <color>
     end if
   end mouseLeave
