R Correlation Matrix doesn't retain property order

I'm using SES 7.5.2 cu1 and would like to use R Correlation matrix with a user defined set of properties. It appears the order of properties is jumbled up when it comes back from R. Is there a way to reorder the records to match the order in my UserSet?

For the time being I'm using the native correlation matrix, so this isn't urgent.

Thanks!
