ActionScript 3.0 :: Control Mouse Click Events In A Multi-dimensional Array?

I have a question regarding the use of mouse clicks events in a multi-dimensional array (or a "2D" array as we refer to them in Java and C++).
 
Background
 
I have an array of objects each with a corresponding mouse click event. Each object is stored at a location ranging from [0][0] to [5][8] (hence a 9 x 6 grid) and has the specific column and row number associated with it as well (i.e. tile [2][4] has a row number of 2 and a column number of 4, even though it is on the third row, fifth column). Upon each mouse click, the tile that is selected is stored in a temporary array. The array is cleared if a tile is clicked that does not share a column or row value equal to, minus or plus 1 with the currently targeted tile (i.e. clicking tile [1][1] will clear the array if there aren't any tiles stored that have the row/column number

[0][0], [0][1], [0][2],
[1][0], [1][1], [1][2],
[2][0], [2][1], [2][2]

or any contiguous column/row with another tile stored in the array, meaning that the newly clicked tile only needs to be sharing a border with one of the tiles in the temp array but not necessarily with the last tile stored).
 
Question
 
What is a clean, tidy way of programming this in AS3? Here are a couple portions of my code (although the mouse click event isn't finished/working correctly):
