There is Good and Easy news;
To run a script developed for Elements there are two methods that work.
1 - With an image open in Elements...
File Menu --> Open -->
(in the dialog box select 'Enable all documents')
then select script_name.jsx
script_name.jsx being any script you want to run.
2 - With an image open in Elements...
Drag the script onto the Elements application icon
NOTE: In Elements 14+ on Mac OS X, you can also drag and drop the script file into the image that is open in Elements.
Elements doesn't seem to have access from within the application to select a script. Although, as of Elements 14+, there is a 'Scripts' folder for Elements, that is found;
[in Windows]
C:/Program Files/Adobe/Photoshop Elements version/Presets/Scripts
[in Apple]
Adobe Photoshop Elements version --> Support Files --> Scripts
For Elements Load Styles Use Styles
