Goodness! Given the trauma of the event, and your goldfish's good fortune that your parents were at home and able to save him and think quickly about where to put him until they quickly/fortunately were able to get him a new tank, it seems as though he's been lucky only to have an injured scale - so well done all round.
*However*, this is where you must now be careful for the next few weeks at least - the stress of the event, plus the damaged scale, will likely reduce his immune system, and make him more susceptible to disease such as finrot setting in.
This risk will be compounded even more with the likely mini-cycle that your tank will be undergoing (due to the loss of beneficial bacteria which process his waste - this beneficial bacteria resides in the substrate, decor, tank walls but mostly in the filter and specifically the filter media) or even full cycle that it may be undergoing (if you've had to put in a new filter and/or new filter media). It'll be very important, therefore, that you follow this guide https://www.fishkeeping.co.uk/articles ... ammonia-nitrite-spike.htm
More generally, and once the situation has settled, it's best if you can do a water change weekly (rather than every 10 days or a fortnight) - and keep ammonia and nitrite at 0 at all times (which may mean even more frequent or larger water changes).
Hope that helps but do get back to us if you have any further questions at all or if he looks as though he's getting worse. I'll keep my fingers tightly crossed for him.
