Copy paste anchored objects in a table

Oh, and what is very helpful:

The parent of an anchored object is a Character Object.

Example 1:

A text frame with an anchored object (the magenta square).
The text frame is selected.

If you ask for the count of characters in the text frame:

app.selection[0].characters.length;

The answer is "5"!
The anchor, that is indeed the anchored rectangle, is treated as a character.

If you select the anchored object and ask for its parent:

app.selection[0].parent;

The answer is "[object Character]".

To move such an anchored object without loosing its anchordness, you have to move the character.

In the above case, the character is characters[0] of the text frame. Or more precise, the characters[0] of texts[0] (all formatted text in the text frame) of the text frame. You also could go a step backward and say: in this case it's the characters[0] of texts[0] of the parentStory of the text frame

To move it somewhere else (e.g. to a cell of a table), you must move it to another Text object.
Every insertion point is a text object (like every character).

Example 2:

A table comes into play:

The text frame is still selected.
And the following code will move the anchored object (indeed the character) to the table:

var myTextFrame = app.selection[0];
var myTable = myTextFrame.parentStory.tables[0];
myTextFrame.characters[0].move(LocationOptions.AFTER, myTable.cells[0].insertionPoints[0]);

Situation after executing the snippet:

Hope that helps,
