Allow users to sort log categories by anomaly score

[mukeshelastic]

Describe the feature:
The log categories are automatically sorted by message count as shown below. We'd like to change the default sort order to maximum anomaly score to allow user to spot critical anomalies easily and also allow sorting by message count and trend percentage. All three, max anomaly score, message count and trend percentage are primary sort orders only i.e. there is no nested sort order of first order being max anomaly score and then by message count.

This would be a welcome enhancement. I would really like to sort by anomaly score.
