The default numeral glyphs are all the same width, to ensure that tables of numbers line up and look pretty (fixed-width spacing).
However, you'll be please to know that there /are/ "alternate" glyph representations with proportionally-spaced numerals in the font set already. These can either be accessed via an alternate method, or in the case that your software doesn't support the alternate glyph methods, the proportionally-spaced digits are also exposed in the private-use area as U+F800 to U+F809.
Please could you have a look at the attached PDF and confirm that the spacing is what you had in mind.
