Q&A - Question

This could also be handled in Excel if I could find a way to perform a spatial join in Tatuk Editor. Eg, join the feature information between the two layers. 

You can check our Binning script that creates polygon layer with hexagonal shapes. New layer contains attribute Density with a number of shapes from existing point layer within each hexagon. I know it is not exactly what you need, but you can see how to create a loop through two layers and count the shapes. We also want to create a new script with a functionality that you described, so please keep up to date with the Editor versions. 
 

I guess you want a little change. The binning process creates hexagons. You want an extra column in your layer B with the amount of points of layer A inside each polygon.
Do you need a ready to use function or do you need a small script to do this for you?

I can drop you a small script to do this.
You can drop me an email on dvhooren@smalltogo.com
