Arabic Numerals Showing in Reverse Order in RTL (Arabic) Course - Results Slide

I'm building a bilingual eLearning course in Storyline 360, and I'm running into a problem with Arabic-Indic numerals (٠١٢٣٤٥٦٧٨٩) in the Arabic version of the results slide.

The course uses JavaScript to convert scores to Arabic numerals and display them using custom variables (e.g., %ArabicScore%, %ArabicPassingScore%). The script works and numerals appear - but they are displaying in reverse order, e.g.:

Instead of: ١٠٠
I'm seeing: ٠٠١

Has anyone successfully displayed correctly ordered Arabic numerals in an RTL Storyline course?

Any suggestions or workarounds would be greatly appreciated. Happy to share my .story file
