Inconsistencies within RTF template conditions

Hi,

I'm trying to use the following in an RTF template to select between two blocks of text.

<?choose:?>

<?when:CONTRACT_LENGTH_DAYS<=‘90’?><?call:Conditional_BlockA?><?end when?>

<?when:CONTRACT_LENGTH_DAYS>‘90’?><?call:Conditional_BlockB?><?end when?>

<?end choose?>

The value of CONTRACT_LENGHT_DAYS in the sample XML (exported from Fusion) is 394.

The above fails the logic returning Conditional_BlockB.

By manually editing the value in the XML it seems the above logic only works while the CONTRACT_LENGTH_DAYS value is 99 or less.

My guess is I'm missing some kind of formatting/padding, assuming this is even possible within RTF templating.
