JS uses length on arrays and strings. Anytime you have an array (be it a list, etc) the number of items is denoted as .length
It makes no sense to have Qt use count in similar situations. As Thiago mentioned length, size and count are all analogous in the C++ API, so I don't know how/why they are ambiguous. I write quite a bit of JS code (server and mobile) and it seems rather arbitrary to continue to use count. 

Specific places: 
All models. DelegateModel, DelegateModelGroup, ListModel, etc.
