How to make a draggable object snap into place?

Question

I'm new to Flash (sort of - I used it a bit back in 1999-2000, but it's changed a LOT since then). I'm making an educational game for my company that involves dragging labels from a word-bank to their correct position on a diagram. I want the kids to be able to drag any one of the five labels and move them to any one of five marked positions on the diagram. I'm using Flash CS5 with Actionscript 3. I used code snippets, so that each individual label has the following code associated with it:
movieClip_1.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
movieClip_1.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
function fl_ReleaseToDrop(event:MouseEvent):void
movieClip_1.stopDrag();
Is there any code that I could add in there to make the objects then snap into positions when dragged near them? Note that there are five possible positions for them to snap to. The coordinates for those are:
X
Y
299.75
235.90
775.40
244.65
421.15
447.45
804.15
484.85
437.15
599.60
Here is a screenshot of the area of the game that this is concerning to give you an idea of what I'm talking about:
Thanks for any help you can give me.

Answer 1

It might help if I give ALL of my code for this project. Here it is:
movieClip_1.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
     movieClip_1.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
function fl_ReleaseToDrop(event:MouseEvent):void
     movieClip_1.stopDrag();
movieClip_2.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_2);
function fl_ClickToDrag_2(event:MouseEvent):void
     movieClip_2.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_2);
function fl_ReleaseToDrop_2(event:MouseEvent):void
     movieClip_2.stopDrag();
movieClip_3.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_3);
function fl_ClickToDrag_3(event:MouseEvent):void
     movieClip_3.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_3);
function fl_ReleaseToDrop_3(event:MouseEvent):void
     movieClip_3.stopDrag();
movieClip_4.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_4);
function fl_ClickToDrag_4(event:MouseEvent):void
     movieClip_4.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_4);
function fl_ReleaseToDrop_4(event:MouseEvent):void
     movieClip_4.stopDrag();
movieClip_5.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_5);
function fl_ClickToDrag_5(event:MouseEvent):void
     movieClip_5.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_5);
function fl_ReleaseToDrop_5(event:MouseEvent):void
     movieClip_5.stopDrag();
answers_but.addEventListener(MouseEvent.CLICK, fl_ClickToPosition);
function fl_ClickToPosition(event:MouseEvent):void
     answersflyin.x = 230.00;
     answersflyin.y = 187.50;
hide_but.addEventListener(MouseEvent.CLICK, fl_ClickToPosition_2);
function fl_ClickToPosition_2(event:MouseEvent):void
     answersflyin.x = 693;
     answersflyin.y = 865.8;
clear_but.addEventListener(MouseEvent.CLICK, fl_ClickToPosition_3);
function fl_ClickToPosition_3(event:MouseEvent):void
     movieClip_1.x = 112;
     movieClip_1.y = 246.55;
     movieClip_2.x = 112;
     movieClip_2.y = 327.85;
     movieClip_3.x = 112;
     movieClip_3.y = 415.55;
     movieClip_4.x = 112;
     movieClip_4.y = 495.5;
     movieClip_5.x = 112;
     movieClip_5.y = 578.25;
     answersflyin.x = 693;
     answersflyin.y = 865.8;
stop();
That all works really well, too, except that the objects don't snap into place. Other than that, I'm able to drag each of the 5 movie-clips onto the board, arrange them as I like, click one button to show correct answers, another to hide answers, and another to sweep the board clean.
