[Building Sakai] Gradebook grading scale question

[Fischbein, Scott A.]

Hi all,
We're converting from 2.7.0 to 2.8-x, and have run into an issue with our existing (and future) Gradebooks:

Our existing grading scales seemed to have lost their indexing order, despite (as far as I can tell) the continued presence of the correct "GRADE_IDX" in the GB_GRADING_SCALE_GRADES_T table.

We have a grading scale that goes from A+ to C-, and then the next value should be Y, and then other values below that... (see below for the values). This was working find previously, but the "Y" value, which should come directly after the C-, now shows up at the bottom instead (ie: the grade scales values are being displayed in alphabetical order, ignoring the "GRADE_IDX" value.

This is the case for existing Gradebooks (ie: for converted course sites) as well as for freshly created sites.

If anyone can provide an explanation, or a suggestion on where to look to try to investigate the issue further, it would be greatly appreciated.

Thanks,
