Using pure html inputs

Is there any issue with using my own html inputs in my CF7 form? The data is correctly captured, so I want to check if there is more I need to know.

For example:
<label><input type=”radio” name=”radio-1″ value=”555″ checked=”checked”>FOO</label>
<label><input type=”radio” name=”radio-1″ value=”777″>BAR</label>

I need to do this so I can have a numeric “value” but a text “label”.
I have tried using Pipes, however pipes don’t display the numeric value in the source code – and I need to get that with javascript.
