  Is this what you mean?

  WITH pass1

  AS (

  -- First number the ActionTypes giving priority to HELLO lines

  SELECT *

  , ROW_NUMBER() OVER (PARTITION BY AccountNum, ActionType ORDER BY ISNULL(NULLIF(ActionType,'HELLO'),'') ,DataAction) AS n1

  FROM ActionDetails

  )

  , pass2

  AS (

  -- Next number the intermediate actions using the newly numbered HELLO actions to partition the data

  SELECT *

  , ROW_NUMBER() OVER (

  PARTITION BY AccountNum

  , n1 ORDER BY DataAction

  ) AS n2

  FROM pass1

  )

  SELECT AccountNum

  , DataAction

  , ActionType

  , CASE ActionType

  WHEN 'HELLO'

  THEN n1

  ELSE NULL

  END AS ActionStart

  , convert(VARCHAR, n1) + CONVERT(VARCHAR, n2) AS ActionCounter

  FROM pass2

  ORDER BY AccountNum

  , DataAction
