This behavior causes metadata plugin to not work properly if a node is fetched from Ajax and inserted into DOM. All child script tags will be grouped and moved to the bottom of the parent node. The script should check for type attribute of script tag to make sure it is of type 'text/javascript'. Some people uses script tags for other purposes such as storing json data, with type as 'application/json' or 'text/x-json', and the position of the script tag is important in this case.
