Your assertion is correct, with the new ability to see active settings 
it’s actually not that difficult to debug what goes on.

Open a new HTML document and then ⌃⌘T (Bundles → Select Bundle 
Item…). Switch to Settings (⌘}) and type ‘increaseindent’. 
You’ll see there is just one item matching here, the one from the HTML 
bundle. You can select Edit to inspect its scope selector (text.html).

Now type <style> and again bring up the settings inspector (I realize 
now it should be “live”). Now there are two items matching, with the 
new one from the Source bundle eclipsing our HTML bundle’s settings 
item.

This is because the scope is now “text.html source” (which you can 
see with ⌃⇧P) and the source bundle’s settings are scoped to 
“source”, which in this case is more specific (deeper), so it wins.

To make the HTML setting the one that wins, we can change it’s scope 
selector to: text.html, text.html source

However, if we change <style> to <script> then indent misbehaves again. 
Looking in our settings list we can see that the JaveScript bundle’s 
setting is now the one taking precedence, that’s because it is 
targeting ‘source.js’ which is more specific than just ‘source’, 
so we must change the HTML item’s scope selector to: text.html, 
text.html source, text.html source.js

I hope the above makes sense.
