Note that is not the same thing as an alias (created by the Finder). They are different file types with different capabilities. For Terminal use you (in general) want the former and the latter for launching through Finder and other apps.
 

Alfred (by design) won’t read that file by default (and neither will most apps).
 

Great that you got it working! That solution is the way to go if you only have one need (seems to be the case). If your needs ever grow to more apps (unlikely since the non-Cask side of Homebrew is moving to have fewer GUI apps), there is a workflow for that.

@Nat Harari Drag the relevant folder into your search scope in the Default Results preferences to include apps from that folder into your results.
 
Alternatively, if you just want one app from an obscure folder and would prefer not to add anything else to the scope, you can create a nickname workflow like this for a one-off file you want to open:

Thanks! I just added it. I admit: I completely missed the "Advanced" button. It was around 7am when I asked so it was before that when I was asking. I just dragged and dropped an .org file into the pop-up window and it seems like it recognised the type automatically. I'll give it time to catalog everything and then try searching again.
 
Thank you very much. 👍😀

You should be able to create a file filter. Just drag in one of your .org files into the file types list, set a keyword and you should be good to go. You can also further narrow your scope if want to designate a specific folder if that is where your .org files reside. Here are some screenshots of a workflow i use to search taskpaper files.
