Scan is also useful for this kind of thing...

s = "ScriptName:changeTests Pass:15 Fail:0 Total:15"
p s.scan(/(\w+):(\S+)/)
# ==> [["ScriptName", "changeTests"], ["Pass", "15"], ["Fail", "0"], 
["Total", "15"]]

To deal with the full string:

s = "send data StartTime: 20090413 13:41:53.000 ScriptName:changeTests 
Pass:15 Fail:0 Total:15"
a = s.scan(/(\w+):\s*([\s\d:.]+|\S+)/)
p a
# ==> [["StartTime", "20090413 13:41:53.000 "], ["ScriptName", 
"changeTests"], ["Pass", "15 "], ["Fail", "0 "], ["Total", "15"]]
a.shift
a.each {|key,val| puts "#{key} = #{val}"}

# ==>
# ScriptName = changeTests
# Pass = 15
# Fail = 0
# Total = 15
