Why do you conflate Actions and Scripts?
Had the Actions been saved or were they only part of the prefs?
If the latter you could try to salvage
~/Library/Preferences/Adobe Photoshop CS6 Settings/Actions Palette.psp
The default locations for Actions would be
/Applications/Adobe Photoshop CS6/Presets/Actions
~/Library/Application Support/Adobe/Adobe Photoshop CS6/Presets/Actions/
