The verb 'sort' is widely used in British English to mean 'deal with' a situation. It isn't wrong and it isn't lazy. For example, anyone who has been on a train anywhere in the UK, or even just passed through a station, will have seen this sign everywhere and heard this announcement many times:
See it. Say it. Sorted.
This slogan is part of a public safety campaign encouraging passengers to inform rail staff about anything suspicious which they see. Here, 'sorted' means 'Problem solved'.
If it's good enough for the British Transport Police, it's good enough for me.
