[TxMt] Syntax match pattern

I seem to be having a terrible time getting my match pattern to work for Forth syntax coloring. FYI, in Forth the only delimiter between words are space|tab. Trying to setup a pattern to highlight comparision words for example I have: { name = "Comparision Operators"; fontStyle = (bold); foregroundColor = "#0066CC"; match = "\s(and|or|xor|0=|0>|0<|0<>|\s>\s|<|<>|=|u<|u>)\s"; },

Where I am trying to say find a space followed by one of the following words followed by white space.

But in my test file only some of the words are highlighted when all of them should be as in the following example. What am I doing wrong?
