Sort on

  translate(.,"OUEHRANSMTWF", "1234569")

if you want Sunday last, or

  translate(.,"OUEHRANSMTWF", "1234560")

if you want Sunday first. Not tested.

Another approach is to sort (numerically) on 

  string-length(substring-before("MON TUE WED THU FRI SAT SUN", .)) 

For a cleaner solution, use an XSLT 2.0 function (or an XSLT 1.0
extension function) to map "MON" to 1, "TUE" to 2, etc.
