Adding href to a mark cancels out aggregation

Question

I'm working on a dual y-axis Vega-Lite bar chart that I hope you can see here. (The code is replicated below).

I have a basic CSV dataset.

I feel there may be an underlying issue that is being masked/caused by automatic/default aggregation, but without the line "aggregate": "min" (line 26 & 47), the bar chart suggests the highest cost is >12,000, where the max data value is actually 5,099.99. This happens to the Score values too.

I need a hyperlink on each bar, but when I add the line "href": {"field": "url", "type": "nominal"}, Vega seems to ignore "aggregate": "min". The example has href added to the X-axis, I have tried adding it to both Y-axes with the same result.

Another issue I have, that maybe a question for another day, is that the sort is ignored, or at least, I cannot get it to sort by Score from small to large.

If anyone could point me in the right direction, I'd be most grateful.
