Jens,

The keyword is +towgs84, not +towgs!  With this fixed I get the same
result as ESRI.

cs2cs +proj=latlong +datum=WGS84 +to +proj=tmerc +ellps=bessel \
    +lat_0=0 +lon_0=13.333333 +k=1.000000 +x_0=0 +y_0=-5000000 \
    +towgs84=577.326,90.129,463.919,5.1366,1.4742,5.2970,2.4232 -r
47.487218 12.254853
-81220.59       261502.07 -47.76
