The easiest way to solve this problem without any code modifications (I'm tired of permanently applying workarounds for Mapscript bugs...) is to set the MINSCALE to 4999 (or 4999.999) if you want to have a maximum (or minimum in MS logic) scale of 5000 used for the slider. I do not see any drawbacks for this setting.
