Tag coloring priority changed from 1.1.1 to current version

I use a dedicated color for different tags. In the last version, when an interval has multiple tags the interval would use the color of the _first_ sorted tag. I used numbers as a prefix to make the tag that I wanted to be sorted first, so the interval would take that color. However, in the current version it seems that the interval takes the color of the _last_ sorted tags. With this change my coloring system doesn't work anymore. Is there any way that I could change that? Thanks.
