. loc mylist "1 2 3"

. mata: strtoreal(tokens(st_local("mylist")))
       1   2   3
    +-------------+
  1 |  1   2   3  |
    +-------------+


or, if you want to create a Stata vector,


. mata: st_matrix("foo", strtoreal(tokens(st_local("mylist"))))

. mat li foo

foo[1,3]
    c1  c2  c3
r1   1   2   3


For more info, see -help mata functions-; in particular, the Stata  
interface functions and string functions.
