Stahanov,
I've had this problem before using a similar style case. The way I handled it was as follows:
First take exact measurements on how big your existing piece of cloth is in your current display case. Once you have them pay a visit to your local sewing goods or craft store and purchase a matching color of cloth. Then have them cut it to your specs or take it home and cut it yourself. Once at home simply insert the cloth over or underneath your existing cloth.
This added piece acts as a spacer and takes up the excess room between the foam core and the glass. This helps secure the medals better because it's a tighter fit. Therefore, it holds them in place. To get it just right you might have to add or subtract more spacers or add spacers underneath the foam core. I think handling it this way could solve your problem.
