Try this:
<$wikify name=number text={{budgetDelta}}>
<$set name=csscolor
filter="[<number>sign[]match[-1]then[color:red;font-weight:bold]else[color:black;]]">
<span style=<<csscolor>>><<number>></span>
</$set>
</$wikify>
Notes:
1) Use $wikify instead of $set. This allows the contents of
{{budgetDelta}} to be parsed by the formula plugin rather than just
retrieving the formula text
2) Set "csscolor" rather than "cssclassname". This uses literal CSS styles
rather than references to classname declarations
3) use "style=<<csscolor>> to apply the computed styles
