Feel bad, upset about imminent script (6,1)

I believe the answer is:

linear a

'script' is the definition.
(I know that Linear A is a script)

'feel bad upset about imminent' is the wordplay.
'feel bad' becomes 'ail' (I've seen this in another clue).
'upset' says the letters should be written backwards.
'about' indicates putting letters inside.
'imminent' becomes 'near' (I've seen this in another clue).
'ail' back-to-front is 'lia'.
'lia' going around 'near' is 'LINEAR A'.

(Another definition for linear a that I've seen is " script yet to be read".)

I've seen this clue in The Guardian.
