I believe the answer is:

I'm a little stuck... Click here to teach me more about this clue!

'earning scrutiny?' is the definition.
I can't judge whether this defines the answer.

'least charitable about holy person' is the wordplay.
'least charitable' becomes 'meanest' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'holy person' becomes 'st' (short for saint).
'meanest' going around 'st' is 'MEANS-TEST'.

Can you help me to learn more?

(Other definitions for means test that I've seen before include "Financial assessment for statesmen" , "form of qualification" , "resources check" , "financial review" , "Check on financial status" .)
